Question

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 = `sqrt ("s" ("s" - "a")("s" - "b")("s" - "c"))  "2ab"`

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)

(iii) double area (double diagonal 1, double diagonal 2) with two double arguments, returns the area of a rhombus using the formula :

area = `1/2` (diagonal 1 × diagonal 2)

Answer 1

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

The variable description is as follows:

1.	a	double	to enter side of the triangle
2.	b	double	to enter side of the triangle
3.	c	double	to enter side of the triangle
4.	s	double	to store the value of s in area formula used.
5.	r	double	to store the value of r in area formula used.
6.	area	double	to store area of various shapes
7.	a	int	to enter side of trapezium
8.	b	int	to enter side of trapezium
9.	height	int	to enter height of trapezium
10.	diagonal 1	double	to enter diagonal of rhombus
11.	diagonal 2	double	to enter diagonal of rhombus
