WebArea of a Regular Polygon. Theorem: Area = 1 2 n a s = 1 2 p a. P = perimeter. a = apothem. The area of the triangle is 1 2 a s, so the area of the regular polygon, which has n triangles, is n times the area of the triangle. Can also be written as: Area = n r 2 sin ( 180 ∘ n) cos ( 180 ∘ n) n = number of sides. r = radius length.
