Step-by-step explanation:
Area of a rectangle is
.
We know the width, W, is
and we know the area is
.
Inputting this in our formula above we get:

L is a an expression such that when you multiply it to
gives you
.
is a difference of squares and can be factored using:
.
.
So L=x-3 and W=x+3.
To calculate this, we have to divide 2 1/2 by 8.
first, i wil turn 2 1/2 into fraction:
it's

and if we divide this by 8, we multiply the denominator by 8:

and this is the answer!
