The formula looks pretty easy: count the points "i" inside, count the points "b" on the edge ("boundary"), and plug the counts into i + (b/2) - 1. The answer is the area. You can see a proof here and do an activity with it here. What part do you need explained more? Thanks.I have read in easycalculation site that using pick's theorem, area of the polygon can be calculated by joining the lattice points...Need more explanation on this.
