Area of Square in Python. Writing a Python program to calculate the area of a square is a fundamental exercise that can help beginners understand the basics of mathematical operations and user input in Python.

## Table of Contents

## Formula of Area of Square

The formula for the area of the square is-

*Area = side x side*

## Writing the Python Code for Area of Square

Open your text/code editor and create a new file named ‘area_square.py’. Then follow these steps to write your program.

### Prompt the User for the Side Length

First, you need to get the length of the square’s side from the user. You can use the `input()`

function for this purpose and since` input()`

return a string, You will need to convert this input into a number (float or integer) to perform mathematical operations.

`side_length = float(input("Enter the length of a side of a square "))`

### Calculate the Area

Next, calculate the area of the square using the formula mentioned earlier.

`area = side_length * side_length`

### Printing the Result

Finally, display the result using the `print()`

function

`print("The area of square is = ",area)`

## Python Program for Area of Square

```
side_length = float(input("Enter the length of a side of a square "))
area = side_length * side_length
print("The area of square is = ",area)
```

Congratulations!! You have just written a simple Python program to calculate the area of a square. This exercise not only demonstrates how to perform mathematical calculations in Python but also introduces basic concepts such as user input and output, variable usage, and type conversion.

**Happy Coding & Learning**
