This looks simple...for 14 the perimeter is x+3+x+3+2x-1+2x-1. Simplified is 6x+6-2. Which is 6x+4.

Thank me if it looks right!

For 15...2y+3+2y+3+x+3+x+3...Which is 4y+12+2x.

To find x, you divide both sides of the equation by 12.20. This would look like this:
12.20x/12.20 =372.10/12.20 . Then, the answer you get is 30.5, so. X=30.5
