Question

Write a Java program to find the perimeter of rectangle and ask the user to input length and width.

Answer 1

//TestBlock.java starts here

import java.util.Scanner;

public class TestBlock {

       public static void main(String[] args) {

              Scanner scan = new Scanner(System.in);

              //Getting the input from user

              System.out.print("Enter the length of Rectangle: ");

              double length = scan.nextDouble();

              System.out.print("Enter the width of Rectangle: ");

              double width = scan.nextDouble();

              //Perimeter of a square = 4 * side

              System.out.println("Perimeter: "+ 2*(length + width));

       }

}

//TestBlock.java ends here

Output:
