Answer:

Width = 12   Length = 9

Step-by-step explanation:

We have to first find an equations with the given variables:

w = 2L - 6

Now apply the area format:

Length * Width

Since the area is 108 square inches

108 = l * w

108 = l(2l-6)

108 = l(2l) + l(-6)

108 = 2l^2 - 6l

Simplify:

(l-9) * (l+6) = 0

Since no number can be negative

w = 2*9(L)-6

w = 12

l=9
