Question

The legnth of a rectangle is 3 less than twice the width. If the perimeter of the rectangle is 36 inches, what are the dimensions of the rectangle in inches?

Answer 1

Answer:

w = 7

l = 11

Step-by-step explanation:

let 'w' = width

length would be '2w-3'

P = 2l + 2w

36 = 2(2w-3) + 2w

36 = 4w-6 + 2w

36 = 6w - 6

42 = 6w

w = 7

length is 2(7)-3, which equals 14-3 or 11

Check:

7 + 7 + 11 + 11 = 36

14 + 22 = 36

36 = 36
