Pentagon Surface Area Formula

Pentagon is the five-sided polygon with five sides and angles. It can be sectored into five triangles. You can find the surface area by knowing the side length and apothem length. The page provides the Pentagon surface area formula to calculate the surface area of the pentagon. To find the surface area of a pentagon, just multiply the side length with apothem length and then multiply the obtained value with the integer 5 and divide the resultant value by the integer 2.

Formula:

S = (5 / 2) L x A


Where,

S = Surface Area of a Pentagon
L = Length of Side
A = Apothem
