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.
