Python Program to find area of square

A square is a closed two-dimensional figure having 4 equal sides. Each angle of a square is 90 degrees. The area of a square is the space enclosed within its four sides. In this problem, we are given the side of a square, and we have to find the area of the square. In this tutorial, we are going to find the area of a given square in Python using different approaches.

Example 1

Input: side = 6 units
Output: 36 square units

Using the formula to calculate the area of the square: side × side = 6 × 6 = 36 square units

Example 2

Input: 0
Output: 0

If the side length is zero, the square does not exist as a two-dimensional figure, and hence, there is no area.

Example 3

Input: side = 12 units
Output: 144 square units

Using the formula to calculate the area of the square: side × side = 12 × 12 = 144 square units.

Below are different approaches to finding the area of the square

• Using the Direct Formula Approach
• Using Function

Using the Direct Formula Approach

We use the direct formula to calculate the area of the square. The formula for calculating the area is: Area = side × side. After calculating the area, we return the result.

Steps for Implementation

• We first take the side length as input.
• Now, use the formula for area = side × side.
• Return the calculated area.

side = 5
area = side * side
print(f"The area of the square with side {side} is: {area}")

The area of the square with side 5 is: 25

Using a Function

We use a function to calculate the area of the square. The logic and formula remain the same, but encapsulating the logic in a function makes it reusable and more modular.

Steps for Implementation

• Create a function that calculates the area using the formula.
• Pass the input side length as an argument to the function.
• Output the calculated result.

def calculate_area(side):
 return side * side
side = 6
area = calculate_area(side)
print(f"The area of the square with side length {side} is: {area}")

The area of the square with side length 6 is: 36
