You can put this solution on YOUR website!
Let A=area
Let w = width
Let L = length
-
Description is, w=L%2B6.
wL=A
%28L%2B6%29L=A
A=L%5E2%2B6
This is really all that can be done unless you have further information. You only have enough information to make a formula for A in terms of w or A in terms of L; if you solve the described information for L and then substitute for L instead.
