    Answer:

    w=12

    l=20

    Step-by-step explanation:

    The area can be found using the following equation:

    A=lw

    Given the information provided, we are also told the following:

    l=w+8

    Therefore, we can plug in our length and our area:

    240=w(w+8)\\240=w^2+8w\\\\w^2+8w-240=0

    We can solve by using the quadratic formula.

    w=\frac{-8+\sqrt{8^2-4(1)(-240)} }{2(1)}=12 \\\\

    w=12, so w+8=20.
