The perimeter of an irregular polygon is the sum of all sides. So, add the sides.

Same as we did before @Buttercup214 

We add, what do we get?

..the perimeter of a REGULAR polygon would be ns, or the number of sides times the length of each side, but in your case the side lengths are different, so simply add the lengths of each side

P=20.9 cm + 22 cm + 39.8 cm + 16.2 cm = 98.9
