Shoelace's theorem

WebPick's theorem (or rule) easily calculates the area (surface) of a polygon with $ b $ vertices built on a lattice, a 2D grid of points with integer coordinates (points with equal distances). If all $ b $ vertices of the polygon (vertices can be flat) are grid points and the polygon has $ i $ points inside itself then Pick's formula indicates that the polygon area $ A $ is equal to $$ … WebHow to apply the Shoelace Formula / Shoelace Method to find the area of a polygon in an x-y plane
