## McGraw-Hill Math Grade 4 Answer Key Chapter 10 Lesson 6 Finding Perimeter

Calculate

Find the perimeter of each figure.

Question 1. 40 meters

Explanation:
Perimeter of a rectangle = (2 x length) + (2 x width)
Length of the given figure = 16 m
Width of the given figure = 4 m
Perimeter = (2 x l) + (2 x w)
= (2 x 16) + (2 x 4)
= 32 + 8
= 40
So, perimeter of the given rectangle is 40 meters.

Question 2. 46 kilo meters

Explanation:
Perimeter of a rectangle = (2 x length) + (2 x width)
Length of the given figure = 13 km
Width of the given figure = 10 km
Perimeter = (2 x l) + (2 x w)
= (2 x 13) + (2 x 10)
= 26 + 20
= 46
So, perimeter of the given rectangle is 46 kilometers.

Question 3. 32 inches

Explanation:
Perimeter of a square = (2 x length) + (2 x width)
Length of the given figure = 8 in
Width of the given figure = 8 in
Perimeter = (2 x l) + (2 x w)
= (2 x 8) + (2 x 8)
= 16 + 16
= 32
So, perimeter of the given square is 32 inches.
