Heron's Formula provides us with the area of triangle provided we know all of its sides(a, b, c).
\Delta = \sqrt{ s ( s-a ) ( s-b ) ( s-c ) }, \ s = \frac{1}{2} ( a + b + c ).
Let's say the three sides are 3, 4, 5.
Then s = \frac{1}{2} ( 3 + 4 + 5 ) = 6 \\
\Delta = \sqrt{ 6 \times 3 \times 2 \times 1 } = 6
