#include <iostream>
using namespace std;
 
    int main()
    {
        int width, length, area, perimeter;
        cout << "\n\n Find the Area and Perimeter of a Rectangle :\n";
        cout << "-------------------------------------------------\n";
        cout<<" Input the length of the rectangle : ";
        cin>>length;
        cout<<" Input the width of the rectangle : ";
        cin>>width;
        area=(length*width);
        perimeter=2*(length+width);
        cout<<" The area of the rectangle is : "<< area << endl;
        cout<<" The perimeter of the rectangle is : "<< perimeter << endl;
        cout << endl;
        return 0;
    }
Sample Output:
Input the length of the rectangle : 23
Input the width of the rectangle : 45
The area of the rectangle is : 1035
The perimeter of the rectangle is : 136
