### Find the area of polygon

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.

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.
