Bretschneider's Formula
This calculator uses Bretschneider's Formula to solve for the area of a quadrilateral where the side lengths and the length of the diagonals are known. The formula used is:
Area = 1/4 * sqrt(4p2q2 - (b2+d2-a2-c2)2)Where:
- a = side length
- b = side length
- c = side length
- d = side length
- p = diagonal length
- q = diagonal length
