The perimeter is 41.7.
We first find the distance between each vertex using the distance formula:
We now find the perimeter by adding all of the side lengths:
14+7.81+19.92 = 41.73 ≈ 41.7

To find x you would cross multiply, multiply the x with 100 and the 15 with the 20%.
100x = 300
Now to find x you would just divide both sides by 100.
x=3
