Fix the bug in the following Python program.
def calculateArea(width, height):
 return width * height

length = 8
breadth = 10
area = calculateArea(length)
print("Area of the rectangle:", area)
def calculateArea(width, height):
 return width * height

length = 8
breadth = 10
area = calculateArea(length, breadth)
print("Area of the rectangle:", area)
