       System.out.println("Enter the side of square");
       double side = sc.nextDouble();
       double perimeter = 4 * side;
       double area = side * side;
       System.out.println("Perimeter of square is " + perimeter);
       System.out.println("Area of square is " + area);
   }
}

40. Write a program to display cost of painting the four walls of a room.

import java.util.Scanner;

class FourWalls {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter the length of room");
       double length = sc.nextDouble();
       System.out.println("Enter the breadth of room");
       double breadth = sc.nextDouble();
       System.out.println("Enter the height of room");
       double height = sc.nextDouble();
       double cost = (length * breadth * height) / 500;
       System.out.println("Cost of painting the four walls of a room is " + cost);
   }
}

41. Write a program to display simple interest.

import java.util.Scanner;

class SimpleInterest {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter the principal amount");
