You will have to divide the polygon into triangles, or know some of the interior angles, because four or more known sides does not uniquely determine a polygon. Brahmagupta's formula is similar to Heron's formula; Brahmagupta's formula can be used to find the area of a quadrilateral given the side lengths and two opposite interior angles.
