Am I doing this right?

Am I doing this right? Converting this into 1 line of code

Square.cs 
namespace Treehouse.CodeChallenges
{
    class Square : Polygon
    {
        public double SideLength => 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;
        }
    }
}

Only thing I see is this:

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

Since you're using the => notation, you shouldn't need the curly braces.
