15 16

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

using System;

class sample3{
    
    static void Main(string[] args){
    int area = 0;
    int around = 0;
    int a;
    int b;
    
    string[] nums = Console.ReadLine().Split(' ');
    
    a = int.Parse(nums[0]);
    b = int.Parse(nums[1]);
    
    area =  a*b;
    around = ((a*2) + (b*2));
    
    Console.WriteLine("{0}{1}",area, around);
    }
