Herons Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.
Let a,b,c be the lengths of the sides of a triangle.
Using Heron's formula this is the calculation to find the triangles area.
Area= √(p(p-a)(p-b)(p-c)
where p is half the perimeter: p= (a+b+c)/2
