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).
