A rectangular garden has a length that is twice its width. The dimensions are increased so that the perimeter is doubled and the new shape is a square with an area of 3600 square feet. What was the area of the original garden, in square feet?
When the perimeter is doubled the scale factor = 2
Original area = New Area / Scale Factor^2 = 3600 / 2^2 = 3600 / 4 = 900
