## Understanding Pentagon Area

In the realm of Mathematics, a pentagon is a polygon with 5 sides. It can be categorized as a regular pentagon or an irregular pentagon. In a regular pentagon, all sides and angles are of equal measure. The formula to calculate the area of the regular pentagon is:

Area of pentagon = [(5/2) × s × a] square units.

Here, “s” represents the side length, and “a” denotes the apothem length.

An alternative formula for calculating the area of a regular pentagon is:

Area of regular pentagon = 1.72 × (Side)² square units.
