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. WebA regular pentagon is a polygon whose five sides are of equal length. The interior angle of a regular pentagon is 540∘ 540 ∘ so an interior angle is equal to 108∘ 108 ∘. The perimeter of this polygon is five times its side (s) ( s) and its area is equal to: A= 1 4√5√5+2√5s2 A = 1 4 5 5 + 2 5 s 2.
