Question 2.
McGraw Hill Math Grade 5 Chapter 10 Lesson 7 Answer Key Finding the Area of a Rectangle 27
Answer:
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
Answer:
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.

Answer:
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.
McGraw Hill Math Grade 5 Chapter 10 Lesson 7 Answer Key Finding the Area of a Rectangle 29
Answer:
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
Answer:
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?
Answer:
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.
