Syntactic sugar

I'm sure my code's right, but I'm still getting "Did you convert area to a single line?"

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;
        }
    }
}

I'm not sure what method you are using to evaluate the code for correctness, but the actual syntax for a single-line property would have a "fat arrow" and no "return" keyword:

        public double Area => SideLength * SideLength;
