Question

What is Heron's formula?​

Answer 1

Answer:  The Herons formula is a formula developed by a guy called " Hero of Alexandria".

The formula helps us to find the area of triangle when all the sides are given. The formula goes like this:-

area = $\sqrt{s(s-a)(s-b)(s-c)}$    

a, b & c are the 3 sides of the triangle.

s =  semi perimeter or $\frac{a+b+c}{2}$
