 cout << "\\\\ Find the Area and Perimeter of a Rectangle :\\"; 
 cout << "-------------------------------------------------\\"; 
 cout<<" Input the length of the rectangle : "; 
 cin>>lngth; 
 cout<<" Input the width of the rectangle : "; 
 cin>>width; 
 area=(lngth*width); 
 peri=2*(lngth+width); 
 cout<<" The area of the rectangle is : "<< area << endl; 
 cout<<" The perimeter of the rectangle is : "<< peri << endl; 
 cout << endl; 
 return 0; 
 }
