With help of Pick's formula one can determine the area f of an polygon on a grid,
depending on the two parameters i and r.

The parameter i is the number of grid points inside the polygon, r is the number of
grid points on the edge of the polygon.

Vary the polygons and try to find out the function f = F(i, r).
