Answer 1

Language used:

Python Programming

Note:

Please do check the attachments given below to have a look at the process of evaluation and interpretation of code in IDLE.

Program:

def circle():

   print("You choose Circle...")

   radius=int(input("enter the radius : "))

   print("Area of the circle with the radius of ",radius," units is", 3.14*            (radius**2),"square units.")

def square():

   print("You choose Square...")

   side=int(input("enter the size of a side of a square : "))

   print("Area of the square with the a side of ",side," units is",side**2,"square units.")

def rectangle():

   print("You choose Rectangle...")

   length=int(input("enter the length of the rectangle : "))

   breadth=int(input("enter the breadth of the rectangle : "))

   print("Area of the rectangle with length and breadth ",length, " ",breadth," units is",length*breadth,"square units.")

print("Menu-\n"

       "1. Circle\n"

       "2. Square\n"

       "3. Rectangle\n")

x=int(input("Enter the corresponding number of a shape given in the menu, whose area you wants to calculate : "))

if x==1:

   circle()

elif x==2:

   square()

elif x==3:

   rectangle()

else:

   print("Wrong Input!")

Explanation:

We create a menu and take a number as an input that denotes the choice. Based on the choice, we make the corresponding shape's function call, that takes the needed inputs and prints the area.

Inputs:

Menu-

1. Circle

2. Square

3. Rectangle

For Circle:

Enter the corresponding number of a shape given in the menu, whose area you wants to calculate : 1

You choose Circle...

enter the radius : 5

For Square:

Enter the corresponding number of a shape given in the menu, whose area you wants to calculate : 2

You choose Square...

enter the size of a side of a square : 5

For Rectangle:

Enter the corresponding number of a shape given in the menu, whose area you wants to calculate : 3

You choose Rectangle...

enter the length of the rectangle : 2

enter the breadth of the rectangle : 3

For Wrong Input:

Enter the corresponding number of a shape given in the menu, whose area you wants to calculate : 9

Outputs:

For Circle:

Area of the circle with the radius of  5  units is 78.5 square units.

For Square:

Area of the square with the a side of  5  units is 25 square units.

For Rectangle:

Area of the rectangle with length and breadth  2   3  units is 6 square units.

For Wrong Input:

Wrong Input!
