The length of rectangle is 4 feet less than twice its width. Find the dimensions if the perimeter is 100 feet.

l= 2w - 4, 2l+2w =100. or l + w = 50

2w - 4 + w = 50 ; 3w = 50 +4 ; w = 54/3 = 18

l = 2w - 4 = 2 * 18 -4 = 36 -4 =32

Length =32 ; Width = 18

l= 2w - 4, 2l+2w =100. or l + w = 50

2w - 4 + w = 50 ; 3w = 50 +4 ; w = 54/3 = 18

l = 2w - 4 = 2 * 18 -4 = 36 -4 =32

Length =32 ; Width = 18
