When I run this program I get "break outside loop" . can I know where I'm wrong?

Question

import math
print ('1. Find the area of square')
print ('2. Find the area of rectangle')
print ('3. Find the area of circle')
print ("4.Exit")
ch=int(input("Enter your choice"))
if (ch==1):
s=int(input('Enter length of the side'))
a=s*s
print('Area=',a)
elif (ch==2):
l=int(input('Enter length='))
b=int(input('Enter breadth='))
a=l*b
print ('Area=',a)
elif (ch==3):
r=int (input ('Enter radius='))
a=2*math.pi*r
print ('Area=', a)
elif (ch==4):
break

Answer 1

Well, you don't have a loop... Why do you need to check ch==4?

Answer 2

You dont need break.remove it.
Also you can shorten the code e.g print(s*s)
