Question

The length of a rectangle is 5 inches less than twice its width. The perimeter of the rectangle is 60 inches. Which system of equations can

be used to determine the length, L, and the width, W, of the rectangle?

Answer 1

Explanation:

L=2W-5 and P=2(L+W) is the system

Substituting L=2W-5 into P=2(L+W) gives you

2(2W-5+W)=P=60

2(3W-5)=60

3W-5=30

3W=35

W=35/3, L=2W-5

L=55/3
