Question

Write a program to enter length and breadth of a rectangle and calculate its Area(Ixb) and perimeter (2(1+b)). (4M)​

Answer 1

Java Program :-

import java.util.*;

public class Rectangle

{

public static void main(String args[ ] )

{

Scanner sc = new Scanner(System.in);

double a = 0.0, p = 0.0;

double l = 0.0, b = 0.0;

System.out.println("Enter the length");

l = sc.nextDouble();

System.out.println("Enter the breadth");

b = sc.nextDouble();

a = l * b;

p = 2*(l + b);

System.out.println("Area =" +a);

System.out.println("Perimeter =" +p);

}

}
