B. width 33 feet: length 35 feet
C. width 27 feet; length 56 feet
D.width 22 feet: length 46 feet

Answer 1

D. width 22 feet: length 46 feet

Explanation:

width: w

length: 2w + 2

perimeter = 2L + 2W

136 = 2(2w + 2) + 2w

136 = 4w + 4 + 2w

136 = 6w + 4

132 = 6w

w = 22

width: w = 22

length: 2w + 2 = 2(22) + 2 = 46
