}}

Answer 2

$\huge\mathfb{Required program :-}$

import java. util.* ;

class Computer

{

void input ()

{

Scanner sc = new Scanner ( System.in ) ;

System. out. println (" Enter the length and breadth of the rectangle : ") ;

int l = sc.nextInt() ;

int b = sc. nextInt() ;

double a ;

}

void cal ()

{

a = l * b ;

}

void dis ()

{

System.out.println( " The area of the rectangle is : "+a) ;

}

public static void main ()

{

Computer obj = new Computer () ;

obj. input () ;

obj. cal () ;

obj. dis () ;

}
