Programming Example

Design a class to overload a function area( ) as follows:

  1. double area (double a, double b, double c) with three double arguments, returns the area of a scalene triangle using the formula:
    area = √(s(s-a)(s-b)(s-c))
    where s = (a+b+c) / 2
  2. double area (int a, int b, int height) with three integer arguments, returns the area of a trapezium using the formula:
    area = (1/2)height(a + b)
  3. double area (double diagonal1, double diagonal2) with two double arguments, returns the area of a rhombus using the formula:
    area = 1/2(diagonal1 x diagonal2)

        // Test area calculation for a triangle
        double triangleArea = geometry.area(3.0, 4.0, 5.0);
        System.out.println("Triangle Area: " + triangleArea);
        
        // Test area calculation for a trapezoid
        double trapezoidArea = geometry.area(5, 7, 4);
        System.out.println("Trapezoid Area: " + trapezoidArea);
        
        // Test area calculation for a rhombus
