where did i go wrong here

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()
        {
        get
        {
        return Square(base)*2;
        }
        }
    }
}
Polygon.cs
namespace Treehouse.CodeChallenges
{
    public class Polygon
    {
        public int NumSides { get; private set; }

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

A computed property should not have () after the name. And the "get" method shouldn't refer to the class itself (and won't need "base", either).

The "get" method should should return the square of "SideLength".

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

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

}

am i getting closer?

When I said "the "get" method shouldn't refer to the class itself" I meant it would not use the term "Square".
An easy way to square a number is to multiply it by itself.
