Answer 1

Answer:

import java.util.Scanner;

public class Square {

public static void main(String[] args) {

 // Taking inputs from user

 Scanner sc = new Scanner(System.in);

 System.out.print("Enter the Length: ");

 double length = sc.nextDouble();

 sc.close();

 double area = length * length;

 double perimeter = 4 * length;

 double diagonal = Math.sqrt(2) * length;

 

 System.out.println("Area: " + area);

 System.out.println("Perimeter: " + perimeter);

 System.out.println("Length of diagonal: " + diagonal);

}

}
