Solution in C# (judge verdict: Accepted)

public class Hello{
    public static void Main(){
        
        var line = System.Console.ReadLine();
        string[] array = line.Split(' ');
        int a = int.Parse(array[0]);
        int b = int.Parse(array[1]);
        
        int menseki = a * b;
        int length = a*2 + b*2;
        
        System.Console.WriteLine(menseki + " " + length);
    }
