An irregular polygon measures different side length on each side. The perimeter is the total distance around the length of the polygon. If you want to know the answer to the question of "How do you find the perimeter of an irregular polygon?", refer the perimeter of an irregular polygon formula given below. From this circumference of an irregular polygon formula, it is obvious that just adding the length of each of its sides will give the circumference.

The above-given perimeter of an irregular polygon formula will be a useful one for the mid school students to refer for their examination purpose. The range of output you get will be dependent on the units of inputs you use.
