Function Overloading - Area Program - ICSE 2014 Computer Science

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

(ii) 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)

class Overload{
    public static double area(double a, double b, double c){
        double s = (a + b + c) / 2;
        return Math.sqrt(s * (s - a) * (s - b) * (s - c));
    }
    public static double area(int a, int b, int height){
        return 1.0 / 2 * height * (a + b);
    }
    public static double area(double diagonal1, double diagonal2){
        return 1.0 / 2 * (diagonal1 * diagonal2);
    }
}
