why doesnt this work

not sure why this isnt working

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 double Scale => SideLength *= factor;

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

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

The method signature should not change. In the original, "Scale" had a parameter and returned "void":

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