The area of a regular polygon can be found using different methods, depending on the variables that are given. Commonly, one is given the side length \(s \), the apothem \(a\) (the distance from center to side--it is also the radius of the tangential incircle, often given as \(r\)), or the radius \(R\) (the distance from center to vertex--it is also the radius of the circumcircle). The rectangle has an area of 15. Example: When each square is 1 meter on a side, then the area is 15 m 2 (15 square meters) Square Meter vs Meter Square. The basic unit of area in the metric system is the square meter, which is a square that has 1 meter on each side: 1 square meter. Be careful to say "square meters" not "meters squared": Jan 18, 2024 · The formula for regular polygon area looks as follows: Regular Polygon Area = n × a² × cot(π/n) / 4; where n is the number of sides, and a is the side length.
