Rectangle Perimeter Word Problem

Question

The length of a rectangle is three times the width. The perimeter of the rectangle is 32 inches. What is the area of the rectangle (in square inches)?

Answer 1

L=3W

2L+2W = 32

2(3W) + 2W = 32

6W + 2W = 32

8W = 32

W = 32/8 = 4

L =3W = 3(4) = 12

Area = LW = 12(4) = 48 in^2 = 48 square inches
