HELP

Ashley and Michael want to design and build a rectangular garden. They have 108 feet of fencing for the border, and they want their garden’s length to be twice its width. What will be the dimensions of their garden?
A. 12ft × 24ft
B. 18ft × 36ft
C. 27ft × 54ft
D. 36ft × 36ft

Answer 1

Perimeter is 2L x 2W or L + L + W + W

A) 12(2) + 24(2) = 72
B) 18(2) + 36(2) = 108
C) 27(2) + 54(2) = 162
D) 36(2) + 36(2) = 144 (and one side is not even twice the length of the other)

Answer: B
