Shape Area Calculation System

The assignment requires implementing a shape area calculation system in Python. The system should take input from the user to select the shape and provide parameters for each shape. It then calculates the area of the selected shape using pre-defined functions for each shape type. The program includes error handling for invalid inputs and provides formatted output with two decimal places.
