Question

The perimeter of a rectangular photograph is 28 inches. If the width of the photo is 5 inches, how tall is the photo?

Answer 1

9 inches.

Explanation:

Since the width of the rectangle is 5 inches, We have to times it by 2 which is 10.

Then deduct it from the perimeter of 28, which equals to 18. We have to divide it by 2 so we can find out how tall each side is. 18 divided by 2=9.

Hope that helps.

Answer 2

Explanation:

p=2L + 2W

28=2L + 2 x 5

28=2L +10

28-10=2L

18=2L

L=9
