Question

The width of a rectangle is 7 less than twice the length. If the perimeter of the rectangle is 43.6 inches, what is the area of the rectangle

Answer 1

2(2l) + 2(2l-7) = 43.6
4l + 4l - 14 = 43.6
8l = 57.6
57.6/8 = 7.2
Length = 7.2
7.2 x 2 = 14.4
43.6 - 14.4 = 29.2
29.2/2 = 14.6
Width = 14.6
Area = length x width
14.6 x 7.2 = 105.12 inches
105.12 inches
