Question

The perimeter of a rectangle is 84 in. The length is 12 inches less than twice the width. Find the length and width of the rectangle

Answer 1

W=16

L = 2(16)-6 = 32-6 = 26

Explanation:

width = W

length = L= 2W-6

P = 2L+2W

84=2(2W-6) + 2W

84= 4W -12 + 2W

84 = 6W -12

84 + 12 = 6W

96 = 6W

W=16
