Question

The perimeter of a rectangle is 38 inches. If the width of the rectangle is 7 inches, what is the length?

Answer 1

12 inches

Explanation:

7 + 7 + y = 38

14 + y = 38

y + 14 = 38

y + 14 - 14 = 38 - 14

y = 24

24 ÷ 2 = 12

Check:

7 + 12 + 7 + 12 = 38

Answer 2

l = 12in

Explanation:

Using the formula

`P=2(l+w)`

Solving for l

`l= (P)/(2) - w =(38)/(2) -7=12in`

Therefore, the length is 12 in
