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).Simply so, how do you calculate the area of a polygon?

Write down the

**formula**for**finding**the area of a regular**polygon**. To find the area of a regular**polygon**, all you have to do is follow this simple**formula**: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides.What is the formula for the area of a polygon?

In your exam, you might be asked to find angles of

**polygons**. The**formula**for calculating the sum of the interior angles of a regular**polygon**is: (n - 2) × 180° where n is the number of sides of the**polygon**. For any**polygon**, count up how many triangles it can be split into. Then multiply the number of triangles by 180.What is the formula for regular polygon?

The area of a

**regular polygon**is given by the**formula**below. area = (½)(apothem)(perimeter) Several other area**formulas**are also available.**Regular Polygon Formulas**. n = number of sides.
