Answer 1

#include<iostream>

using namespace std;

class Triangle
{
	float h;
	float base;
public:
	Triangle(float _h,	float _base) :h(_h), base(_base) {}
	float GetHeight() const { return h; }
	float GetBase()const { return base; }
};

class Area
{
public:
	float operator() (const Triangle& t)
	{
		return 0.5*t.GetBase()*t.GetHeight();
	}
};

int main()
{
	Triangle tr(10, 20);
	Area a;
	cout<<"Area of triangle is "<< a(tr);
}
