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

public class Rectangle {
  static void Main(string[] args) {
    var line = System.Console.ReadLine().Trim().Split(' ');
    int a = int.Parse(line[0]);
    int b = int.Parse(line[1]);

    System.Console.Write(a*b);
    System.Console.WriteLine(2*(a+b));
  }
}
