Write a method called triangleArea that accepts three integer values that represent the three lengths of a triangle. The method should then return the area of the triangle back as a double. For example the call triangleArea(7, 6, 5) would return 14.6969. To compute the area of a triangle use Heron's Formula: Area of a triangle = LaTeX: \sqrt{s\left(s-a ight)\left(s-b ight)\left(s-c ight)}s ( s a ) ( s b ) ( s c ) where LaTeX: s=\frac{\left(a+b+c ight)}{2}s = ( a + b + c ) 2. Then test your method by finding the area of the triangles (5,6,7) , (12,13,14) and (300,400,550) and showing the results.
