Answer 2

Program:

import java.io.*;

public class Main{

     public static void main(String args[]){

           System.out.println("Perimeter of the rectangle with lenght 14.5cm and breadth as 17.8cm is : "+(2*14.5*17.8)+"cm.");

     }

}

Output:

Perimeter of the rectangle with lenght 14.5cm and breadth as 17.8cm is : 516.2cm.

Explanation:

1. since the perimeter of rectangle is 2lb
2. so i calculated 2 x 14.5 x 17.8
3. and printed the value directly
4. so it make less lines
5. and it will allocates less space when compared to initializing variables and passing values to them

----- Hope this helps
