    Suppose that the width is w ft. Then the length is 4 w ft. (Possessive: its . "it's" is a contraction of "it is".) So w * 4 w = 144 , w^2 = 26 , w = 6 The room is 6' * 24' .

    w^2 = 36 Width = 6 ft Length = 24 ft

    l x w = 144 4w^2 = 144 w^2 = 36 w = 6 The length of the rectangle is 24 ft and its width is 6 ft.

    area = length * width = 4*width^2 so 4*width^2 = 144 sq feet ==> width^2 = 36 ==> width = 6 feet and length = 4*6 = 24 feet
