Im not sure what im doing wrong

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

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

        public double Area(double sideLength)
        {
         get
         {
           return SideLength * sideLength
         }
        }
    }
}
Polygon.cs 
namespace Treehouse.CodeChallenges
{
    public class Polygon
    {
        public int NumSides { get; private set; }

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

You're close, but:

  • a computed property doesn't take an argument
  • the computation should be made entirely with the stored "Sidelength"
  • the "return" statement should end with a semicolon
