You will be completing two tasks:

1) Find the area of a triangle given three sides.

Find the surface area of a cylinder given the radius and height of the cylinder.

Given the starter file (MyAreaCalculations.java), finish the program by writing triangleArea and cylinderSurfaceArea methods based on the given method documentation.

Write a method called triangleArea that accepts the three side lengths of a triangle as parameters and returns the area of a triangle with those side lengths. To compute the area, use Heron's formula, which states that the area of a triangle whose three sides have lengths a, b, and c, is the following. The formula is based on the computed value s, a length equal to half the perimeter of the triangle:

area=s(sa)(sb)(sc)area=s(sa)(sb)(sc) s=a+b+c2s=a+b+c2

Write a method called cylinderSurfaceArea that accepts a radius and height as parameters and returns the surface area of a cylinder with those dimensions. The formula for the surface area of a cylinder with radius r and height h is the following:

surfaceArea=2r2+2rh
