Question

The perimeter of a rectangle is 120 feet. The ratio of the width to the length is 2:3. Find the length and width.

Answer 1

Since the ratio of width to length is 2:3, that is a total of 5 parts.
Multiply this by 2 (P = 2L + 2W) = 10 parts.
120/10 = 12
Each part = 12
W:L

12*2:12*3 = 24:36

CHECK

2(24) + 2(36) ??=?? 120

48 + 72 ??=?? 120

120 = 120 checks

Length = 36 ft
Width = 24 ft
