The shoelace formula or shoelace algorithm (also known as Gauss's area formula and the surveyor's formula) is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane. The user cross-multiplies corresponding coordinates to find the area encompassing the polygon, and subtracts it from the surrounding polygon …

ABC. The shoelace formula gets its name from the arrangement of the coordinates and how they are combined to calculate the area. Arrange the x-y coordinates of the polygon in a (n+1)x2 matrix where the order is determined by a counterclockwise pattern around the perimeter and the starting point is also repeated as the last row in the matrix.
