Mathematica(@mathemetica):Brahmagupta's Formula for the area of a cyclic quadrilateral: A = √[(s − a)(s − b)(s − c)(s − d)] where > a, b, c, d = lengths of the four sides > s = semiperimeter = (a + b + c + d)/2 Applies to any quadrilateral that can be inscribed in a circle (as shown in the diagram).
