math.polygon-area-perimeter Calculator
Calculates the area and perimeter of a regular polygon from side length and number of sides, and approximates to π as sides increase. A regular 100-gon has area within 0.01% of the circumscribed circle — this demonstrates the limiting approach to π.
Inputs
Sides
Count of items or occurrences.
Side Length
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Apothem
Reference formula or conversion factor shown for context.
Results
area (m²)
The computed two-dimensional surface area.
perimeter (m)
The total boundary length of the shape.
