WebSince this is highly variable there is no easy rule for how to do it. The examples below give you some basic approaches to try. 1. Break into triangles, then add 2. Find 'missing' triangles, then subtract 3. Consider other shapes As you can see, there an infinite number of ways to break down the shape into pieces that are easier to manage. WebIf you have zillion of such computation to do, try the following optimized version that requires half less multiplications: area = 0; for ( i = 0; i < N; i += 2 ) area += x [i+1]* (y [i+2]-y [i]) + y [i+1]* (x [i]-x [i+2]); area /= 2; I use array subscript for clarity. It is more efficient to use pointers. Though good compilers will do it for you. only you could prevent forest fires
