WebMar 18, 2024 · If you're trying to find the perimeter of a regular polygon, just use the formula: perimeter = number of sides x the length of any side. Method 1 Finding the Perimeter of a Regular Polygon 1 Check that the sides of the polygon are all the same length. Regular polygons are polygons that have equal sides. WebThe area of a regular polygon can be found using the formula, Area = (number of sides × length of one side × apothem)/2. Observe the following steps for the whole procedure: Step 1: Find the number of sides of the polygon. Step 2: If there is a standard formula for the given regular polygon, apply that.

WebMar 26, 2016 · 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). WebA polygon can be classified into two types, namely: Regular polygons; Irregular polygons In a regular polygon all the sides are of the same measure, and all the interior angles are equal. However, in an irregular polygon the measure of the side lengths and interior angles may have different values.
