Solution in C# (judge verdict: Accepted)

using System;

public class Answer {
    private static void Main(string[] args) {
        string input = Console.ReadLine();
        string output = GetAnswer(input);

        Console.WriteLine(output);
    }

    private static string GetAnswer(string input) {
        string output = "";
        int area = 0;
        int circumference = 0;

        int depth = int.Parse(input.Split(' ')[0]);
        int width = int.Parse(input.Split(' ')[1]);

        area = depth * width;
        circumference = (depth + width) * 2;

        output = $"{area} {circumference}";

        return output;
    }
}
