McGraw-Hill Math Grade 5 Answer Key Chapter 10 Lesson 7 Finding the Area of a Rectangle

Multiply

Find the area of each shape.

Question 1.

Question 2.

The above shape is a square.
Given Side = 74.2 km
Area of the square (A) = Side x Side
A = 74.2 km x 74.2 km
A = 5,505.64 square kilometers
Area of the square is equal to 5,505.64 square kilometers.

Question 3.
A rectangle with a length of 105.7 mm and a width 66.8 mm
Given
length = 105.7 mm
Width = 66.8 mm
Area of the rectangle (A) = length x width
A = 105.7 mm x 66.8 mm
A = 7,060.76 square millimeters
Area of the rectangle is equal to 7,060.76 square millimeters.

Question 4.

The above shape is a square.
Given side = 64 cm
Area of the square (A) = Side x Side
A = 64 cm x 64 cm
A = 4,096 square centimeters
Area of the square is equal to 4,096 square centimeters.

Question 5.

The above shape is rectangle.
Given
length = 81$$\frac{3}{4}$$ in
Width = 47$$\frac{1}{4}$$
Convert the mixed fraction into fraction.
Length = $$\frac{327}{4}$$
Width = $$\frac{189}{4}$$
Area of the rectangle (A) = length x width
A = $$\frac{327}{4}$$ x $$\frac{189}{4}$$
A = $$\frac{61803}{16}$$
Convert the fraction into mixed fraction.
A = 3862$$\frac{11}{16}$$ square inches
Area of the rectangle is equal to 3862$$\frac{11}{16}$$ square inches.

Question 6.
A square with a side that measures $$\frac{4}{5}$$ mi
Given side = $$\frac{4}{5}$$ mi
Area of the square (A) = Side x Side
A = $$\frac{4}{5}$$ mi x $$\frac{4}{5}$$ mi
A = $$\frac{16}{25}$$ square mi
Area of the square is equal to $$\frac{16}{25}$$ square mi.

Question 7.
Which has a greater area: a rectangle that measures 15 m by 17 m or a square with a side that measures 16 m? What is the area of each plane shape?
Given
length of the rectangle = 17 m
Width of the rectangle = 15 m
Area of the rectangle (A) = length x width
A = 17 m x 15 m
A = 255 square meters
Area of the rectangle is equal to 255 square meters.
Given
Side of a square = 16 m
Area of the square (A) = Side x Side
A = 16 m x 16 m
A = 256 square meters
Area of the square is equal to 256 square meters.
The square has the greater area.
