Regular Polygon Area Calculator
Calculate the area of any regular polygon given its number of sides and side length.
Regular Polygons
A regular polygon is a 2D shape where all sides are the same length and all interior angles are equal (e.g., an equilateral triangle, a perfect square, a regular pentagon).
The Area Formula
The area can be calculated using trigonometry: Area = (n × s²) / (4 × tan(π/n)), where n is the number of sides and s is the side length.
Frequently Asked Questions
Does this work for a circle?
A circle is theoretically a polygon with an infinite number of sides. If you enter a very high number of sides, the result will approximate a circle's area.
