What is the area of the regular polygon

A regular polygon is equilateral (it has equal sides) and equiangular (it has equal angles). To find the area of a regular polygon, you use an apothem — a segment that joins the polygon's center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem).

To find the area of aregular polygon, you use an apothem — a segment that joins the polygon's center to the midpoint of any side and that is perpendicular to that side
