Prove heron's formula
Webbwas valid, however it was not nearly as elegantly stated as in Heron™s Formula. Professor Rejto then approached me and asked me if I was willing to try to get to Heron™s Formula from equation (6). I said I would attempt it, and I came up with this alternative means of getting to Heron™s Formula. So, this proof was a joint effort between WebbUsing Heron’s formula, Area of the ΔBCD = = 432 m 2 ∴ Area of field = 2 × area of the ΔBCD = (2 × 432) m 2 = 864 m 2 Thus, the area of the grass field that each cow will be getting = (864/18) m 2 = 48 m 2 Q.5: Find the cost of laying grass in a triangular field of sides 50 m, 65 m and 65 m at the rate of Rs 7 per m2. Solution:

WebbHeron's Formula: a Proof. The area S of a triangle ABC, with side length a, b, c and semiperimeter s = (a + b + c)/2, is given by S² = s(s - a)(s - b)(s - c).. Heron's formula is named after Hero of Alexandria (1 century AD. The formula is a specialization of Brahmagupta's formula for cyclic quadrilaterals. For, after all, every triangle is a cyclic … WebbThe Hero’s or Heron’s formula can be derived in geometrical method by constructing a triangle by taking a, b, c as lengths of the sides and s as half of the perimeter of the triangle. Δ P Q R is a triangle. The lengths of sides of triangle P Q ―, Q R ― and P R ― are a, b and c respectively.
