    read it carefully and the equation will be (3w-4)w = 55m^2 Solve the equation and get the value of W and L

    A=W*L, L=A/W this way you can find the value of L

    put that equation into quadratic formula or simply solve the equations.

    (3w-4)w = 55m^2 3w^2 - 4w - 55 = 0 (3w + 11)(w-5)= 0 w = 5m and L = 11m
