31 3 Area Of Regular Polygons 04 Youtube The previous examples gave you too much information. for these problems, we will only be given length of the radius or apothem. This mathguide video demonstrates how to calculate the area of a regular polygon. visit our text lessons at mathguide lessons .
Area Of Regular Polygons Youtube This lesson gives a detailed view of regular polygons. in addition to identifying terms associated with regular polygons, a few examples regarding area are. Area of a regular polygon formulas. the most popular, and usually the most useful formula is the one that uses the number of sides n n and the side length a a: a = n \times a^2 \times \frac {1} {4}\cot\left (\frac {\pi} {n}\right) a = n × a2 × 41 cot(nπ) however, given other parameters, you can also find out the area: – incircle radius (it. Using the apothem as the height and the polygon side as the base, the area of each triangle can be calculated and summed. therefore, the area regular polygons is equal to the number of triangles formed by the radii times their height: (side length) (apothem length) (number of sides) 2. this lesson gives a detailed view of regular polygons. 3. know the correct formula. the area of any regular polygon is given by the formula: area = (a x p) 2, where a is the length of the apothem and p is the perimeter of the polygon. 4. plug the values of a and p in the formula and get the area. as an example, let's use a hexagon (6 sides) with a side ( s) length of 10.
