Calculate the area of the regular polygon given that the number of sides is 5 and the side length is 3cm Solution.

How to find the area for a regular polygon. A 2r tan π n 2R sin π n Inradius r. If you want to find the area of a regular polygon simply use the formulas described above. The following formulas were used to develop calculations for this calculator where a side length r inradius apothem R circumradius A area P perimeter x interior angle y exterior angle and n number of sides.

Area of a regular polygon The number of square units it takes to completely fill a regular polygon. Area of Regular Polygon. Number of diagonals m.

You may need to calculate the area for a carpet the fabrics needed for a curtain the space available in a house. As shown below this means that we must find the perimeter distance all the way around the hexagon and the measure of the apothem using right triangles and trigonometry. An apothem is also used sometimes to find the area of a regular polygon.

Area of a Hexagon. A r 2 n sin360n2 Square units. How to find the area of a polygon.

If the circum-radius r of the regular polygon is given then. 220 cm 2. However if the polygon is not regular what means it isnt equiangular and equilateral you can.

A regular polygon is a polygon whose all sides and all angles are equal. Finding the area of regular polygon when. Find the area using vertices coordinates.

Area of Regular Polygon Example. A n s a 2 A n s a 2 Lets dive into the details. Therefore the area regular polygons is equal to the number of triangles formed by the radii times their height.

Four different ways to calculate the area are given with a formula for each. ½ x 44 x 10 cm 2. 3 peak angle theta1801-largefrac2nhspace20px at degree.

All vertices of a regular polygon lie on a common circle the circumscribed circle ie. Find the area of a regular polygon with perimeter of 44 cm and apothem length of 10 cm. Side length apothem length number of sides2.

Using the apothem as the height and the polygon side as the base the area of each triangle can be calculated and summed. Area of a Regular Polygon Formula Combine the number of sides n n and the measure of one side s s with the apothem a a to find the area A A of any regular polygon. R 12a cot π n R cos π n Circumradius R.

As we know Area A ½ x p x a here p 44 cm and a 10 cm. 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. A polygon is a closed curve or figure formed by the line segments such that no two line segments intersect except at their endpoints and no two line segments with a common endpoint are coincidentIn other words a simple closed curve made up of only line segments is called a polygon.

Try thisDrag the orange dots on each vertexto resize the polygon. Area Σxᵢ yᵢ₁ -. We perform the calculation of any regular polygon.
