Exercise 2: Add code to the program above so that the modified program will determine whether or not the rectangle entered by the user is a square. Sample Run: Enter the length of a rectangle: 7 Enter the width of a rectangle: 7 The area of the rectangle is 49.00 The perimeter of the rectangle is 28.00 The rectangle is a square.
