Polygon Calculator
Calculate area and perimeter from polygon vertices.
Area
15.5
Perimeter
16.8909
Vertex count
4
Orientation
Counterclockwise
Formula
Area uses the shoelace formula and perimeter adds the side lengths.
Paste polygon vertices as coordinate pairs to estimate area, perimeter, vertex count, and orientation.
