Write a computed property named Area that returns the area of the square.

Which Area should I return??

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 Area;
            }
        }
    }
}
Polygon.cs 
namespace Treehouse.CodeChallenges
{
    public class Polygon
    {
        public int NumSides { get; private set; }

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

:point_right: You should compute and return the area of the square itself.

The area of a square is side × side, or in this case, "SideLength * SideLength".
