How to Find the Area of Regular Polygons (with Examples) from www.wikihow.com

Are you struggling to find the area of a polygon with n sides? Whether you are a student or a professional, calculating the area of a polygon can be a challenging task. In this article, we will explore the formula to calculate the area of a polygon with n sides in a relaxed and easy-to-understand language.

What is a Polygon?

A polygon is a closed two-dimensional shape with straight sides. It can have any number of sides, but the most common polygons are triangles, rectangles, and squares. Polygons can be regular or irregular, depending on the length of their sides and the angles between them.

How to Calculate the Area of a Polygon with n Sides?

The formula to calculate the area of a polygon with n sides is:

Area = (n * s²) / (4 * tan(π/n))

Where:

n is the number of sides of the polygon
s is the length of each side of the polygon
π is the mathematical constant pi (approximately 3.14159)
tan is the tangent function

Example:

Let's say we have a polygon with 6 sides and each side is 5cm long. To calculate the area of this polygon, we can use the formula:

Area = (6 * 5²) / (4 * tan(π/6))

After simplification, we get:

Area = 64.95cm²
