Rectangle Class

You are asked to design a Rectangle class in Python. This class should have two attributes:

  • height - which represents the height of the rectangle

  • width - which represents the width of the rectangle

The class should also include three methods:

  • area - a method that calculates and returns the area of the rectangle, which is the product of the height and the width.

  • perimeter - a method that calculates and returns the perimeter of the rectangle. The formula to calculate the perimeter is 2 * (height + width).

  • diagonal - a method that computes and returns the length of the diagonal of the rectangle.
