If I know all the vertices of a particular polygon/figure, is there a generalized method/formula to calculate the area?

You have to know the order of the vertices too, as otherwise there can be multiple answers –  Henry Jan 27 '12 at 7:53
There is also Pick's theorem. –  Ragib Zaman Jan 27 '12 at 9:08
