Solution in C# (judge verdict: Accepted)

public class Hello
{    
    public static void Main()
    {      
        // 1 行に複数の入力値がある場合の例       
        string [] inputs = System.Console.ReadLine().Split(' ');   
        int a = int.Parse(inputs[0]);     
        int b = int.Parse(inputs[1]);        
        int c = (a * b);   
        int d = (a + b) * 2;       
        System.Console.WriteLine(c + " " + d);  
    }
}
