   import java.util.Scanner;
class AreaOfRectangle {
   public static void main (String[] args)
   {
     Scanner scanner = new Scanner(System.in);
     System.out.println("Enter the length of Rectangle:");
     double length = scanner.nextDouble();
     System.out.println("Enter the width of Rectangle:");
     double width = scanner.nextDouble();
     //Area = length*width;
     double area = length*width;
     System.out.println("Area of Rectangle is:"+area);
   }
}

Output:

  Enter the length of Rectangle:
3
Enter the width of Rectangle:
8
Area of Rectangle is:24.0
