Suppose that the perimeter a rectangle is 54 feet, and the length is 13 feet more than the width. Find the width ractangle, in feet.

Answer:7feet

Step-by-step explanation:

perimeter (p) = 54ft

Width (w) + 13=Length (L)

Perimeter=2xLength+2xwidth

P=2xL+2xw

L=w+13

54=2 (w+13) + 2w

54=2w+26+2w

Collect like terms

54-26=2w+2w

28=4w

Divide both sides by 4

28/4=4w/4

7=w

Width = 7feet
