You are given the length of every side, except for two, that can be easily derived from the others:
- The long horizontal side on top is the sum of the three beneath it, so it is

- The vertical one on the right is, similarly, the sum of the opposite side to the far left, and the two small sides near it:

The sum of all sides, including these two, will give you the perimeter of the polygon.
