Compute a Rectangle's Area

Write a function named rectangle_area(width, height) that returns the area of a rectangle with the given width and height (both numbers).

Examples:

rectangle_area(3, 4)  ->  12
rectangle_area(5, 5)  ->  25

Remember: defining the function does not run it. The grader will call your function with different values, so your function must return its answer.

def rectangle_area(width, height):
    """Return the area of a rectangle with the given width and height
    (both numbers)."""
    pass

def rectangle_area(width, height):
    """Return the area of a rectangle with the given width and height
    (both numbers)."""
    pass
