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 = V/s(s – a)(s – b)(s – c)2ab, %3D, S(S, |, a+b+c, where s =, 2, (ii) double area (int a, int b, int height) with, three integer arguments, returns the area of a, trapezium using the formula:, 5 height (a + b), (iii) double area (double diagonal 1, double, area, %3D, diagonal 2) with two double arguments,, returns the area of a rhombus using the, formula :, area = (diagonal 1 x diagonal 2) [15]
