 Question 177185: The length of a rectangle is twice its width. If the perimeter of the rectangle is 30ft, find its areaAnswer by stanbon(57282)   (Show Source): You can put this solution on YOUR website!The length of a rectangle is twice its width. If the perimeter of the rectangle is 30ft, find its area --------------------------------- Perimeter = 2(L+W) = 30 L + W= 15 -------------------------- But L = 2W, so substitute to get: 2W + W = 15 3W = 15 W = 5 L = 2W = 10 ----------------------- Area = LW = 10*5 = 50 sq. ft. ================================ Cheers, Stan H.
