WebMar 18, 2024 · To calculate the area of a regular polygon, multiply ½ x p (the perimeter) x a (the apothem, or the distance from the center of the polygon to the midpoint of any side). If the polygon is irregular, you’ll need to divide it up into regular shapes (e.g., a rectangle and a triangle), find the area of each part, and add them together. WebApr 14, 2016 · An (older) ESRI algorithm computes the center of mass and, after testing it for inclusion in the polygon, moves it horizontally if necessary until it lies within the …
WebDenote "signed area" of triangle O A B: S O A B = 1 2 ( x A y B − x B y A). It can be derived from cross product of vectors O A →, O B →. If way A B is ↺ (if polar angle of A less than polar angle of B ), then S O A B > 0 ; if way A B is ↻ (if polar angle of A greater than polar angle of B ), then S O A B < 0.
