What will be the output of the following C# code?

 class maths
 {
     public int length;
     public int breadth;
     public maths(int x, int y)
     {
         length = x;
         breadth = y;
         Console.WriteLine(x + y);
     }
     public maths(double x, int y)
     {
         length = (int)x;
         breadth = y;
         Console.WriteLine(x * y);
     }
 }
class Program
{
    static void Main(string[] args)
    {
        maths m = new maths(20, 40);
        maths k = new maths(12.0, 12);
        Console.ReadLine();
    }
}
