Answer to Question #299827 in Python for Eren

Question

write a program that displays the following menu:            

Geometry Calculator

1.     Calculate the Area of a Circle

2.     Calculate the Area of a Rectangle

3.     Calculate the Area of a Triangle

4.     Quit

• The must be a main function that will display the menu and will ask for user's choice.
• For each choice 1, 2 and 3, create an appropriate user-defined function for each task.
• Provide validation for input.

Score will be updated after checking for the following:

• 40 points deduction if there is no user defined function created at all.
• 20 points deduction if all user defined function are void functions and no arguments.
