Louis wants to carpet the rectangle floor of his basement. The basement has an area of 864 square fee. The width of the basement is 2/3 its length. What is the length of Louis's basement?
Maybe the rectangle is a 216x4, so 210/3 is 70 and 6/3 is 2. 72 ft. is one-third of the length, so the width is 144 square ft. and the length is 216ft.
