Find the Area of square in Python

Find the area of square is a basic problem that helps beginners to understand concepts of Python and it also helps to improve their logic.

In this post, we will learn how to find the area of a square in Python by taking input from the user and also writing it using the function but before writing a program let’s see the formula to find area of a square.

Formula for Area of Square

Formula: A = s²

Where A = Area of a Square.
s = length of the side

Algorithm for Area of Square

1. Ask the user to enter the length of the side (side)
2. Create one variable called Area and perform the calculation Area = side**2.
3. At the end print the result (Area).

From the above algorithm, we can easily write a Python program to find the area of a square but before writing a program few programming concepts you have to know:

1. How to input from the user &
2. Arithmetic Operators in Python

Source Code

side = int(input('Enter Length of the Side: '))
Area = side**2
print(f'Area of a Square is {Area}')

Output

Enter Length of the Side: 5
Area of a Square is 25

Now let’s write this program using Python Function.

Find the Area of square in Python Using Function

Before writing this program you should know about:

1. How to input from the user
2. Arithmetic Operators in Python &
3. Python Functions

Source Code

def Area_of_square(s):
    return s**2

side = int(input('Enter Length of the Side: '))
print(f'Area of a Square is {Area_of_square(side)}')

Output

Enter Length of the Side: 7
Area of a Square is 49
