Solution in C# (judge verdict: WA: Presentation Error)

using System;

namespace test{
	class program{
	
	static void Main() {
	string[] tmp = Console.ReadLine().Split(' ');;
	rectangle rect = new rectangle(int.Parse(tmp[0]), int.Parse(tmp[1]));
	Console.Write("{0} {1}",rect.area(),rect.perm());
	}
}
class rectangle{
	int height;
	int width;
	public rectangle(int h, int w){
		height = h;
		width = w;
	}
	public int area(){
		return height*width;
	}
	public int perm(){
		return (height+width)*2;
	}
}
}
