i would like clear code. please

Write a method called triangleArea that Jaccepts 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 = Vs (s a) (s b) (s c) where (a+b+c) 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. could you please possibly help me
