$L=9W+6$ I'm guessing you need an expression for the perimeter, but you didn't state that in your post ... $P=2W+2(9W+6)$

I would note a couple of things: you haven't said what "x" represents, you haven't said what that is supposed to be equal to, and it could be more simply written as 20x+ 12. If, as skeeter suggests, the problem is to write an expression for the perimeter as a function of the width then you need to say "Letting the width be represented by x, the perimeter is given by 20x+ 12."
