The perimeter is 28.
(40 feet)(28 feet) = 1120 square feet.
In order to make sense of this question it is necessary to assume that the area is 28 SQUARE metres and not 28 metres as stated. Then, Length = Area/Width = 28/4 = 7m Then perimeter = 2*(Length + width) = 2*(7 + 4) = 2*11 = 22 metres.
28 meters It would be a square because A = L x W so 49 = 7 x W and the width is 7. Its perimeter is 4*7 = 28 meters.
