x + |y| <= 6. |x|+ y >=3. find no. of integeral points. i could not understand the explainatn provided in crackus50 .. could u provide me with some other easy approach to solve

Hi Nipun,

The solution makes use of Pick's theorem, according to which:

A = I + P/2 - 1, where A is the area of the polygon, I is the number of interior integral points and P is the number of integral points on the boundary of the polygon. Remember that the formula can be used only for polygons.
