How to find the perimeter of a polygon The perimeter of any polygon is the total distance around the outside, which can be found by adding together the length of each side. For example, a quadrilateral whose sides are 12,6,9 and 8, the perimeter is the sum of these, or: Perimeter = 12+6+9+8 = 35 Regular Polygons For regular polygons, where all the sides are the same length, the perimeter is n times the length of any side, where n is the number of sides.
