Paper art promoting Area Word Wonders, a trivia for 7th-grade math students on area calculations.

What is the area of a rectangle with a length of 8 units and a width of 3 units?
16 square units
11 square units
22 square units
24 square units
The area of a rectangle is given by multiplying its length by its width. Multiplying 8 by 3 gives 24 square units, which is the correct area.
Which term best describes the measurement of the surface covered by a shape?
Volume
Perimeter
Length
Area
Area measures the amount of space inside the boundaries of a two-dimensional shape. It is different from perimeter, which measures the boundary length, and volume, which applies to three-dimensional spaces.
What is the area of a square if one side measures 5 units?
5 square units
10 square units
15 square units
25 square units
The area of a square is calculated by squaring the length of one of its sides. Since 5 squared equals 25, the area is 25 square units.
Which formula is used to calculate the area of a triangle?
side × side
base × height
1/2 × base × height
π × radius²
The correct formula for the area of a triangle is one-half multiplied by its base and height. This method works for all triangles regardless of their type.
If a rectangle has an area of 36 square units and a length of 9 units, what is its width?
4 units
5 units
3 units
6 units
The area of a rectangle is the product of its length and width. Dividing the given area (36 square units) by the length (9 units) yields a width of 4 units.
A rectangle has a length that is twice its width. If the area is 50 square units, what is the width?
50 units
10 units
25 units
5 units
Let the width be x; then the length is 2x. The area is given by 2x², and setting this equal to 50 gives x² = 25, so x is 5 units.
What is the difference between area and perimeter in a rectangle?
Area measures space inside, while perimeter measures the boundary length
They are exactly the same calculation
Both are measured in square units
Area is measured along the edge, while perimeter measures space inside
Area is the measure of the space contained within the shape, expressed in square units, whereas perimeter is the total distance around the shape. They are fundamentally different properties of a rectangle.
If a square and a rectangle have the same area, which statement is true?
They can have different perimeters
They always have equal side lengths
Their diagonals are equal
They must have the same dimensions
Even if a square and a rectangle share the same area, their side lengths and overall dimensions can be different. Consequently, their perimeters and other related measurements may not match.
How does doubling the dimensions of a rectangle affect its area?
It increases the area by 200%
It doubles the area
It quadruples the area
It remains the same
Doubling both the length and width of a rectangle multiplies the area by 2 x 2, which equals 4, or quadruples it. This shows the effect of scaling on two-dimensional figures.
A rectangle has a length of 12 units. If its area is 96 square units, what is its width?
14 units
8 units
10 units
6 units
The width of a rectangle can be found by dividing the area by the length. Dividing 96 by 12 gives a width of 8 units.
Which shape's area is calculated using the formula length × width?
Parallelogram
Rectangle
Circle
Triangle
A rectangle's area is found by multiplying its length by its width. Although a parallelogram uses a similar multiplication, the formula specifically uses height (perpendicular to the base) rather than the side length.
In an area word problem, if a garden measures 15 feet by 10 feet, how many square feet of area does it cover?
25 square feet
300 square feet
150 feet
150 square feet
The area of a garden is calculated by multiplying its length by its width. Thus, 15 feet times 10 feet equals 150 square feet.
A parallelogram has a base of 8 units and a height of 5 units. What is its area?
80 square units
40 square units
20 square units
13 square units
The area of a parallelogram is found by multiplying the base by the height. Multiplying 8 by 5 gives an area of 40 square units.
Which of the following formulas is used to find the area of a circle?
2 × π × radius
π × radius²
Radius × diameter
π × diameter
The area of a circle is calculated by multiplying π by the square of the radius. This formula accurately determines the space contained within a circular boundary.
A triangle has a base of 10 units and a height of 6 units. What is its area?
30 square units
16 square units
60 square units
20 square units
The area of a triangle is calculated using the formula 1/2 × base × height. Multiplying 10 by 6 and then taking half gives an area of 30 square units.
A composite figure consists of a rectangle measuring 12 units by 3 units attached to a square with a side of 3 units. What is the total area of the figure?
39 square units
48 square units
45 square units
36 square units
The area of the composite figure is the sum of the areas of the two shapes: the rectangle (12 × 3 = 36) and the square (3 × 3 = 9). Adding these together gives a total area of 45 square units.
If a rectangle's area increases by 100% when both its length and width are increased by the same factor, what is the scale factor applied to each dimension?
2
1.5
√2 (approximately 1.414)
1.2
When both dimensions are scaled by a factor of r, the area becomes r² times the original. For the area to double (increase by 100%), r² must equal 2, implying that r is √2, or approximately 1.414.
A rectangle's length is increased by 20% and its width is decreased by 20%. How does this affect its area compared to the original?
The area decreases by 20%
The area increases by 4%
The area decreases by 4%
The area remains the same
Calculating the new area, we multiply 1.2 (for the increased length) by 0.8 (for the decreased width), which results in 0.96 times the original area. This means the area decreases by 4%.
Given a composite figure formed by a rectangle (length 10, width 4) and an adjoining right triangle (base 4, height 3) sharing a common side, what is the total area?
44 square units
50 square units
46 square units
40 square units
The rectangle's area is calculated as 10 × 4 = 40 square units and the triangle's area as 1/2 × 4 × 3 = 6 square units. Together, they add up to a total area of 46 square units.
If the area of a circle increases by 50%, by what percentage must the radius increase?
50%
25%
Approximately 22.5%
Approximately 15%
Since the area of a circle is proportional to the square of its radius, a 50% increase in area means the new area is 1.5 times the original, so the radius must be multiplied by √1.5, which is approximately 1.225. This corresponds to an increase of about 22.5%.
