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

**Calculate**

**Find the perimeter of each figure.**

Question 1.

Answer:

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.

Answer:

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.

Answer:

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.

Question 4.

Sophia is making a frame for a photo. If the photo is 4 inches by 6 inches, how much wood will she need for the frame?

Answer:

20 inches

Explanation:

Sophia is making a frame for a photo

The photo is 4 inches by 6 inches

Perimeter of a frame = (2 x length) + (2 x width)

Length of the given frame = 4 in

Width of the given frame = 6 in

Perimeter = (2 x l) + (2 x w)

= (2 x 4) + (2 x 6)

= 8 + 12

= 20

So, perimeter of the given frame is 20 inches.
