You know that one side of the yard is 40 feet long, so call this the length.
You also know that the area of the yard is 280 square feet. In order to determine the perimeter, you must know the width of the yard:
A = l x w
280 = 40W=7
Frank fences the two 7-foot sides and one of the 40-foot sides. Therefore, he needs 40 + 2(7) = 54 feet of fence.
