Answer 1

Question:-

• To write a menu-driven program to perform the following

Area of the Rectangle

Diagonal of the Rectangle

Perimeter of the Rectangle

Answer:-

package Coder;

import java.util.*;

public class Rectangle {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int ch;

System.out.println("Enter your choice\n1 for area\n2 for diagonal\n3 for perimeter");

ch = sc.nextInt();

System.out.println("Enter lenght and breadth of a rectangle");

int l = sc.nextInt();

int b = sc.nextInt();

switch (ch) {

case 1:

System.out.println("---Area of Rectangle---");

System.out.println(l * b);

break;

case 2:

System.out.println("---Diagonal of a Rectangle---");

System.out.println(Math.sqrt(Math.pow(l, 2) + Math.pow(b, 2)));

break;

case 3:

System.out.println("---Perimeter of a rectangle---");

System.out.print(2 * (l + b));

break;

default:

System.out.println("Invalid choice");

}

}

}

Variable Description:-

ch---> To accept user's choice

l--->to accept lenght of the rectangle

b--->to accept breadth of the rectangle
