How this calculator works
For a regular polygon, multiply the number of sides by the squared side length and divide by four times tan(pi divided by the number of sides).
Formula
n × s² / (4 × tan(π/n))For a regular polygon, multiply the number of sides by the squared side length and divide by four times tan(pi divided by the number of sides).
Worked example

Assumptions and limitations
- Use compatible units wherever the formula combines physical quantities.
- The calculator applies only the formula and assumptions stated on this page; it does not infer missing domain-specific rules.
- Results use finite-number arithmetic and should be interpreted with appropriate real-world measurement precision.
Methodology & sources
This calculator uses deterministic, versioned calculation logic. The formula and verified examples above are part of the calculation definition used by CalcuMint.

Frequently asked questions
How does the Polygon Area Calculator work?
For a regular polygon, multiply the number of sides by the squared side length and divide by four times tan(pi divided by the number of sides).
What units should I use?
Use mutually compatible units. The result follows the unit relationship implied by the displayed formula.
Is this result deterministic?
Yes. The same validated inputs and calculator version produce the same mathematical result; AI is not used for the calculation.
