Write a program which calculates the area and perimeter of a given rectangle.

Input

The length a and breadth b of the rectangle are given in a line separated by a single space.

Solution in C# (judge verdict: Runtime Error)

using System;

namespace Rectangle
{

	class Rectangle
	{
		static void Main()
		{
			string tmp;
			int x;
			int y;
			int area;
			int length;
			
			tmp = Console.ReadLine();
			
			x = int.Parse(tmp.Substring(0,1));
			y = int.Parse(tmp.Substring(2,1));

			area = x * y;
			length = (x + y) * 2;
			Console.WriteLine(area + " " + length + "\r");
		}
	}
