```hello
I need to rewrite area.py program so that it has separate functions for the perimeter and area of a square, a rectangle, and a circle (3.14 * radius**2).
I am horrible at math and I cannot even figure out what I need to do for this
Any help would be appreciated

All I have is the menu which looks like this

import math
print " "
print "1) Area(SQUARE)"
print "2) Area(RECTANGLE)"
print "3) Area(CIRCLE)"
print "4) Perimeter(SQUARE)"
print "5) Perimeter(RECTANGLE)"
print "6) Perimeter(CIRCLE)"
print "7) Exit"
while True:
python area.py

print "Calculate information about a rectangle"
length = input("Length:")
width = input("Width:")
print "Area",length*width
print "Perimeter",2*length+2*width
print 'To find the area of a rectangle,'
print 'Enter the width and height below.'
print
w = input('Width:  ')
while w <= 0:
print 'Must be a positive number'
w = input('Width:  ')
h = input('Height: ')
while h <= 0:
print 'Must be a positive number'
h = input('Height: ')
print 'Width =',w,' Height =',h,' so Area =',area(w,h)
