public class rectangle{

public static void main(String args[])

{

int width=5;

int height=10;

int area=width*height;

System.out.println("Area of rectangle="+area);

Answer 2

import java.util.Scanner; //importing Java.util package

public class rectangle //class declared

{ //class block starts

public static void main(String [] args) //function declared

{ //function block starts

Scanner in = new Scanner(System.in); //creating object of scanner class

int area, l, b; //variable declared of int data type

System.out.println("Enter length of the rectangle"); //printing message

int l = in.nextInt( ); //function to enter int data

System.out.println("Enter the breadth of the rectangle"); //printing message

int b = in.nextInt( ); //function to enter int data

System.out.println("Area of rectangle =" + (l*b)); //calculating and printing area of rectangle

} //function block ends

} //class block ends
