Question

java program to calculate area and perimeter of rectangle

Answer 1

Answer:

import java.util.Scanner;

class Rectangle

{

public static void main (String args[ ])

{

Scanner sc=new Scanner (System.in);

int ch

System.out.println("Perimeter");

System.out.println("Area");

System.out.println("Enter your choice");

switch(ch)

{

case 1:

int a=0;

System.out.println("enter the length of the rectangle ");

int l=sc.nextInt();

System.out.println("enter the breadth of rectangle");

int b=sc.nextInt();

int a=l*b;

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

break;

case2:

int p=0;

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

int l=sc.nextInt();

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

int b=sc.nextInt();

int p=2(l+b);

System.out.println("perimeter of rectangle="+p);

break;

case default:

System.out.println("You have entered wrong choice ");

}

}

}

this is your answer
