Using C++

need answered withing 2 hours please

using C++ classes and sets.

Only need Step 2 answered, implementing Rectangle.cpp

Point.h #ifndef Point_h #define Point_h class Point{ friend std::ostream& operator d. calculate Area(): This function returns the area of the rectangle. To calculate area, you must first calculate the length of sides of the rectangle. e. calculate Perimeter(): This function returns the perimeter of the rectangle. To be able to calculate that you must again calculate sides of the rectangle. Step 3. Test your classes with the following main.cpp #include #include "Rectangle.h" #include "Point.h" using namespace std; int main(int argc, const char * argv[]) { Point al{3,6}; Point b1{7,6); Point c1{7,3}; Point d1{3,3}; Point a2{5,5); Point b2{9,4}; Point c248,0}; Point d2(4,1); Rectangle rec1{a1, b1, ci,d1}; Rectangle rec2(a2,b2, c2, d2}; cout
