Calculate areas

You want to create a Python program to calculate different areas. To do this, the program will present the option of area to be calculated. The possible options are:

1. Calculation of the area of a square: area = side**2

2. Calculation of the area of a triangle: area = (base * height)/2

3. Calculation of the area of a rectangle: area = side1 * side2

Once the option has been chosen, the necessary data will be requested and the corresponding result will be presented. In the event that the specified option was not correct, the phrase “incorrect value” would be displayed on the screen.

>>> %Run 
    Area (square/triangle/rectangle): square
    Side: 3.56
    The area of the square is: 12.6736
>>> %Run 
    Area (square/triangle/rectangle): triangle
    Base: 18
    Height: 4
    The area of the triangle is: 36.0
>>> %Run 
    Area (square/triangle/rectangle): rectangle
    Side 1: 4.67
    Side 2: 9
    The area of the rectangle is: 42.03
>>> %Run 
    Area (square/triangle/rectangle): hello
    Wrong value
>>> %Run 
    Area (square/triangle/rectangle): square
    Side: -4
    Wrong value

Insist that the students test their programs by giving them example
test executions.
