Question

Sides of cyclic quadrilateral shaped are 72m 150m 154m 80m.find it's area find the total expenses of the cost of tiling is 5rupees square metre

Answer 1

Answer:

Area. where s, the semiperimeter, is s = 12(a + b + c + d). This is a corollary of Bretschneider's formula for the general quadrilateral, since opposite angles are supplementary in the cyclic case. If also d = 0, the cyclic quadrilateral becomes a triangle and the formula is reduced to Heron's formula.
