I think this code is not working correctly. I'm pretty sure my code is correct, but it doesn't compile.

I get a compiler error that it doesn't expect a "return" statement.

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

        public double Area => return 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;
        }
    }
}

It was actually giving you a pretty good hint there!

The single-line version of the "Area" property should not have the word "return" in it:

        public double Area => SideLength * SideLength;
