Brahmagupta Formula Calculator


Brahmagupta formula is named after an Indian astronomer and mathematician who came up with the formula to find the area of inscribed (cyclic) quadrilateral. We can apply Brahmagupta formula to find area of inscribed quadrilateral when we know the lengths of all sides of a quadrilateral a, b, c and d.
