I can help you with this one because I can't see the paper too well. Sorry. This one would be 256.
The perimeter of a shape is when you add up all the sides. I used a calculator to add up all the numbers. The images shows three different forms.
Hope this helps! :)
-2w < -18 <em>change the signs</em>
2w > 18 <em>divide both sides by 2</em>
<h3>w > 9</h3>
