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)
