What is the perimeter of a square with a side length of 5 cm?
20 cm
30 cm
15 cm
25 cm
The perimeter of a square is calculated by multiplying the side length by 4. For a side length of 5 cm, 5 Ã - 4 equals 20 cm.
Which shape has all sides of equal length and four right angles?
Square
Rhombus
Rectangle
Parallelogram
A square is defined by having four equal sides and four right angles. Although rectangles also have right angles, their sides are not necessarily equal.
What does area measure?
The length of a shape
The distance around a shape
The amount of space inside a shape
The speed of an object
Area quantifies the two-dimensional space enclosed within a shape. It differs from perimeter, which is the measurement around the shape.
If a rectangle has a length of 8 units and a width of 3 units, what is its area?
22 square units
11 square units
26 square units
24 square units
The area of a rectangle is obtained by multiplying its length by its width. Here, 8 Ã - 3 equals 24 square units.
What is the formula for the perimeter of a rectangle?
2 * (length * width)
2 * (length + width)
length + width
length * width
The perimeter of a rectangle is calculated by adding the length and width and then multiplying the sum by 2. This formula accounts for both pairs of identical sides.
A square and a rectangle have the same area of 16 square units. If the square has a side length of 4, what could be the dimensions of the rectangle?
8 units by 2 units
5 units by 3 units
6 units by 4 units
7 units by 2 units
A rectangle with dimensions 8 units by 2 units has an area of 16 square units (8 Ã - 2). The other options do not yield the required area.
A triangle has a base of 10 cm and a height of 6 cm. What is its area?
20 square cm
16 square cm
30 square cm
60 square cm
The area of a triangle is given by ½ à - base à - height. Substituting the given values: ½ à - 10 à - 6 equals 30 square cm.
If the circumference of a circle is 31.4 cm, what is its approximate radius? (Use π ≈ 3.14)
5 cm
3 cm
10 cm
15 cm
The circumference of a circle is calculated as 2Ï€r. Dividing 31.4 by 6.28 (which is 2 Ã - 3.14) gives approximately 5 cm.
Which of the following shapes does not have any curved sides?
Semicircle
Pentagon
Circle
Oval
A pentagon is a polygon with five straight sides, unlike circles, ovals, or semicircles which contain curves.
What is the area of a composite figure that consists of a rectangle of 4 cm by 5 cm and a square of side 3 cm attached along one side?
39 square units
17 square units
32 square units
29 square units
Calculate the area of the rectangle (4 Ã - 5 = 20) and add the area of the square (3 Ã - 3 = 9) to get a total of 29 square units.
Which transformation results in a shape that is not congruent to the original?
Translation
Reflection
Rotation
Dilation
Reflection, rotation, and translation are congruence transformations that preserve a shape's size and form. Dilation, however, changes the size of the shape, resulting in a non-congruent figure.
What is the perimeter of a regular hexagon with a side length of 7 units?
42 units
28 units
49 units
36 units
A regular hexagon has 6 equal sides. Multiplying 7 units by 6 results in a perimeter of 42 units.
A rectangle has a perimeter of 24 units and a length of 8 units. What is its width?
8 units
2 units
6 units
4 units
The perimeter formula for a rectangle is 2 Ã - (length + width). Solving 2 Ã - (8 + width) = 24 gives a width of 4 units.
Calculate the area of a trapezoid with bases of 10 units and 6 units and a height of 4 units.
36 square units
40 square units
32 square units
28 square units
The area of a trapezoid is calculated as ½ à - (sum of bases) à - height. Here, ½ à - (10 + 6) à - 4 equals 32 square units.
A composite figure consists of a rectangle measuring 6 units by 3 units and two identical right triangles with legs of 3 units and 4 units attached to its longer side. What is the total area of this figure?
24 square units
32 square units
30 square units
36 square units
The area of the rectangle is 18 (6 à - 3). Each triangle has an area of 6 (½ à - 3 à - 4), so the two triangles add up to 12. Together, 18 + 12 equals 30 square units.
A regular octagon is inscribed in a circle. Which of the following expresses the relationship between the side length of the octagon and the radius of the circle?
The side length equals the radius.
The side length equals R cos(22.5°).
The side length equals 2R sin(22.5°).
The side length equals half the radius.
For a regular octagon inscribed in a circle, the side length is determined by the formula s = 2R sin(π/8), which is equivalent to 2R sin(22.5°). This trigonometric relationship connects the side length directly to the radius.
A complex shape is formed by removing a quarter-circle from a square with a side length of 10 units. What is the area of the remaining figure?
100 + 25Ï€ square units
100 - 25Ï€ square units
25Ï€ - 100 square units
100 - 50Ï€ square units
The area of the square is 100 (10²) and the area of the quarter-circle is 25π (¼ of π à - 10²). Subtracting the area of the quarter-circle from the square gives 100 - 25π square units.
In spatial reasoning, which method is most effective for visualizing the rotation of a three-dimensional object?
Ignoring the object's faces.
Relying solely on algebraic calculations.
Observing the object from a single angle.
Drawing multiple two-dimensional projections.
Multiple two-dimensional projections provide various perspectives of a 3D object, making it easier to understand its rotation and spatial relationships. This method is more effective than observing from just one angle or relying only on formulas.
A regular pentagon and a regular hexagon have equal perimeters. Which shape encloses a greater area?
The pentagon.
They enclose the same area.
It cannot be determined.
The hexagon.
With an equal perimeter, a shape with more sides tends to be closer to a circle and thus encloses a larger area. Therefore, the regular hexagon, having six sides, encloses a greater area than the pentagon.
A rectangular garden has an area of 200 square meters and its length is twice its width. What are the dimensions of the garden?
Width = 12 m, Length = 24 m
Width = 10 m, Length = 20 m
Width = 5 m, Length = 10 m
Width = 8 m, Length = 16 m
Let the width be w and the length be 2w. The area is then 2w² = 200, leading to w² = 100 and w = 10 m. Thus, the length is 20 m.

Grade 4 Area & Perimeter Worksheets Cheat Sheet

  1. Understand Area vs. Perimeter - Area tells you how much space is inside a shape, while perimeter measures the distance around its edges. Nail down this difference early to avoid mixing up formulas and keep your calculations on point. Byju's Guide
  2. Memorize Rectangle Formulas - For rectangles, area = length × width and perimeter = 2 × (length + width). These two go hand‑in‑hand, so practice plugging numbers in until they become second nature. Byju's Rectangle Cheat Sheet
  3. Master Square Calculations - Squares are just a special case of rectangles: area = side², perimeter = 4 × side. That means one formula covers both tasks, letting you breeze through square‑based problems. Byju's Square Tricks
  4. Triangle Area Secrets - Right‑angled triangles use area = ½ × base × height, but other triangles might need Heron's formula or sine rules. Practicing different types helps you spot which method fits each problem. GeeksforGeeks Formulas
  5. Circle Calculations with π - Circles call for π (≈3.14): area = π × radius² and circumference = 2 × π × radius. Remembering these means you can conquer any round‑shape question in one go. Byju's Circle Guide
  6. Apply to Real‑World Scenarios - Find the area of a garden bed or the fence length around your yard to see these formulas in action. Real problems make abstract ideas stick and show you practical uses for your skills. WorkyBooks Practice
  7. Explore the Van Hiele Model - This learning framework guides you through levels of geometric reasoning, from simple shape recognition to advanced property proofs. Climbing these levels boosts your confidence and deepens your understanding. Van Hiele on Wikipedia
  8. Break Down Complex Shapes - Split irregular forms into rectangles, triangles, and circles to calculate area and perimeter piece by piece. This trick turns any wild shape into a familiar puzzle. WorkyBooks Strategy
  9. Sum Up Polygon Perimeters - Whether it's a pentagon or a decagon, the perimeter is just the sum of all its side lengths. Keep a systematic approach - list, add, double‑check - and you'll ace polygon problems every time. Byju's Polygon Pointer
  10. Practice Makes Perfect - Regularly tackle worksheets, timed quizzes, and mixed drills to build speed and accuracy. The more you practice, the more these formulas become second nature, ready for any test or real‑world challenge. WorkyBooks Drills
