I don't get it

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

Instead of modifying SideLength, try creating a new getter method for Area. The area of a square can be calculated by squaring the length of one of its sides.
