I will answer your first question. If you have more than one, you should post them separately.
If we call the length L and the width W, then remember that perimeter is:

We have that the length is 15 more than twice the width, so we can represent length by 2W+15. Thus we have:

So the width is 15 feet. Thus the length would be 2(15)+15=45 feet.
