java program to find perimeter of a rectangle

In perimeter of rectangle java program user enters length and width of a rectangle. Then using the formula to find perimeter of rectangle,

perimeter = 2 * (length + width). Lastly print the perimeter value.

Also read – string concatenation in java

For example,

Input:

Length = 10

Width = 5

Perimeter = 2 * (10 + 5) = 30

Here’s program to find the perimeter of the rectangle,

// rectangle java program
import java.util.Scanner;

public class PerimeterOfRectangleDemo
{    
   public static void main(String []args)
   {
      int length, width, perimeter;
      Scanner sc = new Scanner(System.in);
      System.out.print("Enter length of rectangle : ");
      length = sc.nextFloat();
      System.out.print("Enter width of rectangle : ");
      width  = sc.nextFloat();
      perimeter = 2 * (length + width);
      System.out.println("Perimeter of rectangle : " + perimeter);
      sc.close();
   }          
}



Output:

Enter length of rectangle : 2
Enter width of rectangle : 5
Perimeter of rectangle : 14
