Stuck here

Im kinda of stuck here and im also stuggling with the concept of computing could someone give me some assistance with this?

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

            get
            {
               return SideLength  * 4;
            }

        }

        public Square(double sideLength) : base(4)
        {
            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 "SideLength * 4" is not the formula for computing the area of a square.

The correct formula is the side squared, which is the same as multiplying it by itself ("SideLength * SideLength").
