    In geometry, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle by requiring no arbitrary choice of side as base or vertex as origin.

    Let a,b, and c are sides of a triangle. 

    Then s = (a+b+c) ÷ 2

    s is semi-perimeter of triangle

    Then According to Heron formula

     area of triangle = {tex}\Delta = \sqrt {s(s-a)(s-b)(s-c)}{/tex}
