WebFeb 11, 2024 · The formula for the area of a polygon is always the same no matter how many sides it has as long as it is a regular polygon: area = apothem × perimeter / 2 Just as a reminder, the apothem is the distance between the midpoint of any side and the center. WebMar 25, 2016 · Consider a regular polygon with side length s inscribed in a circle with radius r. Let θ be the measure of a central angle subtended by a side of the regular polygon as shown in the figure below.
