How to find area of polygon.
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.
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.

To find the interior angle sum of a polygon, we can use a formula: interior angle sum = (n - 2) x 180°, where n is the number of sides. For example, a pentagon has 5 sides, so its interior angle sum is (5 - 2) x 180° = 3 x 180° = 540°. Created by Sal Khan.To find the area of a regular hexagon, or any regular polygon, we use the formula that says Area = one-half the product of the apothem and perimeter. As shown … Where n = number of sides. L =Side length of a polygon. R = Radius of the circumscribed circle. Let’s work out a few example problems about the area of a regular polygon. Example 1. Find the area of a regular hexagon, each of whose sides measures 6 m. Solution. For a hexagon, the number of sides, n = 6. There are four ways to calculate the area of a regular polygon. Depending on the data available to you, you can calculate the area of the polygon as follows. Given the Length of a Side (s) = Area = s2n 4tan180 n A r e a = s 2 n 4 t a n 180 n where, s is the length of any side of the polygon and n is the number of sides of the polygon.2 Answers. A robust way to do this is to do a sum of the cross-products of the vertices of each edge. If your vertices are co-planar, this will produce a normal to the plane, whose length is 2 times the area of the closed polygon. Note that this method is very similar to the 2D method linked in your question, which actually calculates a 2D ...In real life examples, you can measure the outside boundary of any closed geometric shape to find its perimeter measurement. But you can also use the following formulas to find the perimeters of other common shapes: Square: length of any side x 4. Triangle: side 1 + side 2 + side 3.

For a non-simple polygon, the formula computes the sum of signed area of all the simple components of the polygon. Your example component has self-intersections, and indeed one components of it, the triangle, contributes twice to the area. A closed figure formed a three or more line segments is called a polygon. Polygons are classified according to the number of sides. Area of a rectangle = length x breadth. Area of a Square = Side x Side = s 2 sq. units.
