Answer 2

Answer:

In geometry, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Unlike other triangle area formulae, there is no need to calculate angles or other distances in the triangle first.

Heron's formula-

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

where

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