Heron's Formula is used to calculate the area of a triangle with the three sides of the triangle. Proof of this formula can be found in Hero of Alexandria’s book “Metrica”. You have to first find the semi-perimeter of the triangle with three sides and then area can be calculated based on the semi-perimeter of the triangle. Determine whether a triangle can be formed with the given side lengths. See wiki if you want details. 18 times the square root of 7 -- this is what we got using Heron's. Then once you figure out S, the area of your triangle-- of this triangle right there-- is going to be equal to the square root of S-- this variable S right here that you just calculated-- times S minus a, times S minus b, times S minus c. That's Heron's Formula right there. Heron's Method (approximation of the square root of a number): 3.1. Main reasons: Computing the square root is much slower than multiplication. Heron’s Formula: A = √ [s (s – a) (s – b) (s – c)] Where “s” is the semi-perimeter of the triangle i.e. -the hypotenuse the equation becomes c = square root (a 2 + b 2) - the side a formula is a = square root (c 2 - b 2) - the side b expression is b = square root (c 2 - a 2) Heron formula for area of a triangle. Heron’s Method is iterative. Hero of Alexandria was a great mathematician who derived the formula for the calculation of the area of a triangle using the length of all three sides.
