♣ HERON'S FORMULA

✍️ It is used to find the area of any triangle if the length of its sides are given.

✍️ The formula is :-

$\sqrt{s(s-a)(s-b)(s-c)}$

where,

s = semi perimeter of the triangle i.e. $\frac{(a+b+c)}{2}$

a, b, and c are the side lengths of the triangle.


✍️ The formula is credited to Hero (or Heron) of Alexandria, who was a Greek Engineer and Mathematician in 10 – 70 AD.


✍️ Amongst other things, he developed the Aeolipile, the first known steam engine, but it was treated as a toy!
