Execute the rectangle class with some modifications:
- add color
and add other shape class like triangle with same attributes of rectangle class
then upload the source files and screenshoot of the run

Answer:
Main.cpp:
#include <iostream>
#include "Rectangle.h"
#include "Triangle.h"
using namespace std;
int main() {
Rectangle r1(5, 6, "blue");
cout << "Length of rectangle: " << r1.getLength() << endl;
cout << "Width of rectangle: " << r1.getWidth() << endl;
cout << "Color of rectangle: " << r1.getColor() << endl;
cout << "Area of rectangle: " << r1.getArea() << "\n\n";
Triangle t1(8, 4);
cout << "Length of triangle: " << t1.getHeight() << endl;
cout << "Width of triangle: " << t1.getBase() << endl;
cout << "Area of triangle: " << t1.getArea() << "\n\n";
return 0;
}
