   -----------------------------------
   Write a program that displays the area and   perimeter of a square that has a side of 5.2 using the following formula:
    area = side * side 
    perimeter = 4 * side

   ==================================== */

    // 2. compute variabel area and perimeter
    float area = side * side,
    perimeter = 4 * side;
    
    // 3. Display area and perimeter calculation results.
    cout << "The area of a square with side length " << side << " is " << area << ". \n"<< endl;
    cout << "The perimeter of a square with side length " << side << " is " << perimeter << "."<< endl;
