Abstract: The authors deduce a formula of the area of a grid point ploygon in the form of complex double integration by means of a formula of the area of a grid point polygon in number theory.In addition the authors derive the formula of integral round a contour via the expression of the area of polugon in analytic set form.And  the complex double integration is studied briefly.

Key words: polygon, complex integer, p-grid point, double integration
