# Heron's Formula

This formula is used to find the area of triangle when its sides are given.

#### Theory:

Consider a triangle ABC having its all three sides with known values, i.e a, b, c.
Here,
* a means side opposite to A.
* b means side opposite to B.
* c means side opposite to C.

Now there is a term 'half perimeter' which is denoted by " s " in this formula.

#### Formula:

And finally the formula is given as:

#### Special Features:

* You do need to calculate height of triangle using complex geometric calculations.
* You just have to put the given sides in the formula and get the answer.
