How to Calculate Regular Polygon Area

Calculate the area of any regular polygon by sides and length.

The Formula

A = ns²/(4·tan(π/n))

The regular polygon area formula uses the mathematical relationship: A = ns²/(4·tan(π/n)). Each variable in the formula represents a measurable quantity that affects the final result.

Step-by-Step Method

  1. 1Identify all input values needed for the regular polygon area calculation.
  2. 2Substitute your known values into the formula: A = ns²/(4·tan(π/n)).
  3. 3Perform the arithmetic operations in the correct order (PEMDAS/BODMAS).
  4. 4Check that your result has the correct units and is within a reasonable range.
  5. 5Verify using the interactive Regular Polygon Area to confirm your answer.
