The number of points, having bothco-ordinates as intergers, that lie in the interior of the triangle withvertices (0,0), (0,41) and (41,0) is :
The number of integral points (integrals poems mean both coordinate should should be integers ) exactly with the interiors of triangle with vertices (0,0),(4,3)and(21,0)
