Easily calculate the area of a regular heptagon with our free online tool. Simply input the side length to get instant, accurate results for your 7-sided polygon. Perfect for geometry students, designers, and anyone needing quick calculations.
Formula:
The area (A) of a regular heptagon can be calculated using its side length (s) with the formula:
A = (7/4) × s² × cot(π/7)
- A = Area of the regular heptagon
- s = Length of one side of the heptagon
- cot(π/7) = Cotangent of the angle π/7 radians (approximately 0.44853)
