How can this problem be raised to a higher level of complexity

**bobpursley**, Wednesday, October 27, 2010 at 4:23pmI am wonder what width and length means..is that the sum, or each?

I will assume it is each width and length.

80+5x)(40+5x)= 80*40+200x+400x+25x^2

but this is an INCREASE of

600x+25x^2 or you do it for x=7
