QUESTION TWO.

$[20$ Marks$]$

$2.$ You are developing a class named ShapeAnalyzer to handle geometric shape calculations for a computer$-$aided design $($CAD$)$ software. The ShapeAnalyzer class includes three overloaded methods named calculateArea$()$ for computing the area of various shapes.

The first calculateArea$()$ method takes a single parameter, which represents the radius of a circle. It should calculate and return the area of the circle.

The second calculateArea$()$ method takes two parameters, representing the length and width of a rectangle. It should calculate and return the area of the rectangle.

The third calculateArea$()$ method takes three parameters, representing the base, height, and side length of a triangle. It should calculate and return the area of the triangle.

$2\mathrm{.}1.$ Implement the ShadeAnalyzer class and write a main$()$ method to test all three overloaded calculateArea$()$ methods and provide sample input and output for each test: $[12$ Marks$]$
