To calculate the area of a regular polygon, square the side length (**s²**) and multiply by the number of sides (**n**). Divide this product by 4 times the tangent of **π/n**. This will give you the area of the polygon.

## Area of Regular Polygon Calculator

The **Area of Regular Polygon Calculator** is designed to help you quickly find the area of any regular polygon by inputting the number of sides and the length of each side. Whether you’re calculating the area of a **5-sided polygon** or a polygon with **16 sides**, this tool uses the standard formulas to provide accurate results.

You can also calculate the area using an **apothem** or radius if given. The calculator is ideal for students, architects, and anyone working with polygons in geometry. It simplifies the process, giving step-by-step results for calculating the area of both regular and irregular polygons.
