Program to find the side length of a square given its area

Write a program to find the side length of a square with given area.

Examples:

Input: Area = 16 square units
Output: Side length = 4 units

Input: Area = 25 square meters
Output: Side length = 5 meters

Approach: To solve the problem, follow the below idea:

The side length of a square can be calculated using the formula: Side length=sqrt(Area)​.

Step-by-step algorithm:

• Calculate the square root of the given area.
• The result is the side length of the square.

Below is the implementation of the algorithm:

#include <cmath>
#include <iostream>

using namespace std;

int main()
{
    double area, sideLength;

    // Example test case
    area = 25.0;

    // Calculate side length
    sideLength = sqrt(area);

    // Output the result
    cout << "Side length: " << sideLength << endl;

    return 0;
}

#include <math.h>
#include <stdio.h>

int main()
{
    double area, sideLength;

    // Example test case
    area = 25.0;

    // Calculate side length
    sideLength = sqrt(area);

    // Output the result
    printf("Side length: %lf\n", sideLength);

    return 0;
}

import java.util.Scanner;

public class SquareSideLength {
    public static void main(String[] args)
    {
        Scanner scanner = new Scanner(System.in);

        // Example test case
        double area = 25.0;

        // Calculate side length
        double sideLength = Math.sqrt(area);

        // Output the result
        System.out.println("Side length: " + sideLength);
    }
}

import math

# Example test case
area = 25.0

# Calculate side length
side_length = math.sqrt(area)

# Output the result
print(f"Side length: {side_length}")

using System;

class Program
{
    static void Main()
    {
        // Example test case
        double area = 25.0;

        // Calculate side length
        double sideLength = Math.Sqrt(area);

        // Output the result
        Console.WriteLine("Side length: " + sideLength);
    }
}

// Example test case
let area = 25.0;

// Calculate side length
let sideLength = Math.sqrt(area);

// Output the result
console.log("Side length: " + sideLength);

Side length: 5
