Can't get passed this. Don't understand what I am doing wrong.

What am I doing wrong?

Square.cs 
namespace Treehouse.CodeChallenges
{
    class Square : Polygon
    {
        public double SideLength { get; private set; }


        public double Area  => SideLength * SideLength;

        public Square(double sideLength) : base(4)
        {
            SideLength = sideLength;
        }

        public void Scale (double factor) => SideLength *= factor;

        }
    }
}
Polygon.cs 
namespace Treehouse.CodeChallenges
{
    class Polygon
    {
        public int NumSides { get; private set; }

        public Polygon(int numSides)
        {
            NumSides = numSides;
        }
    }
}

Did you use the "Preview" button to see the compliler output? It said:

Square.cs(18,0): error CS1525: Unexpected symbol `}'

And that's the issue — you forgot to remove the last close brace from the code you replaced.

No sorry, I didn't use the "Preview". I'll keep that in mind next time. Thank you.
