Regular Polygon Area = (n × s²) / (4 × tan(π/n))
FAQ

A polygon where all sides are equal in length and all angles are equal. Squares, equilateral triangles, and hexagons are common examples.
Can it calculate irregular shapes?
This tool focuses on regular polygons. For irregular shapes (rooms with odd angles, land parcels), use an irregular area tool that takes coordinate points and applies the shoelace formula.
