Rewrite the area2.py program from the Examples above to have a separate function for the area of a square, the area of a rectangle, and the area of a circle (<code>3.14 * radius ** 2</code>). This program should include a menu interface.
<source lang="python">
def square(length):
return length * length
def rectangle(width , height):
return width * height
def circle(radius):
return 3.14 * radius ** 2
def options():
print
print "Options:"
print "s = calculate the area of a square."
print "c = calculate the area of a circle."
print "r = calculate the area of a rectangle."
print "q = quit"
print
print "This program will calculate the area of a square, circle or rectangle."
choice = "x"
options()
while choice != "q":
choice = raw_input("Please enter your choice: ")
if choice == "s":
length = input("Length of square: ")
print "The area of this square is", square(length)
options()
elif choice == "c":
radius = input("Radius of the circle: ")
print "The area of the circle is", circle(radius)
options()
elif choice == "r":
