Understanding This Calculator

Shoelace Formula

Calculate area of a polygon given vertex coordinates.

Area = ½ | Σ(xᵢyᵢ₊₁ - xᵢ₊₁yᵢ) |

Example 1

Triangle (0,0), (4,0), (0,3)

  • Sum 1 (xᵢyᵢ₊₁): 0 + 12 + 0 = 12
  • Sum 2 (xᵢ₊₁yᵢ): 0 + 0 + 0 = 0
  • Area = ½ |12 - 0| = 6

How to Use

  • Enter coordinates of polygon vertices (clockwise or counter-clockwise).
