I wonder if someone can help me find the area of a two-dimensional object in the Cartesian plane when we know the coordinates of each point. For example: I want to calculate the area of a triangle. A (12.34) B (45.89) C (25.35)
I want the general algorithm to detect any 2-D region of an object.
Thank.
Here you go, uses triangulation. This was literally Google’s best result when I looked for a “polygon area with a given set of points." Please do your research before publishing.
