# Change the code below.
# For each function:
#
# 1) take the incoming arguments and try to convert them to numeric values (basic errors people can make), adding additional try/catch statements that provide MEANINGFUL feedback to the user. (3 pts)
# i.e. float(var) or int(var) C
#
# 2) Call the function and test for None. If None or False is passed in for any value, check to see if the value is set, using if/else. If not set, use a print statement to tell the user that they need to pass in a value.

except:
print("Could not calculate area")
return False #False is 0, so it returns that
