How would one solve for: Did you make the 'Square.Area' property with no setter?

How do you get around the above error? I tried to remove the 'private set;' and that does not work. Thanks.

Square.cs 
using System;

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


        public double Area {get; set; }

        public Square(double sideLength) : base(4)
        {
            SideLength = sideLength;
            Area = Math.Sqrt(SideLength);
        }

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

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

It's phrased as a question to make it a hint, but clearly the code has a "set;" statement but the challenge is expecting the new property to not have a setter. So you'll need to remove it.

Also, the currently empty getter needs to have a code body that will return the calculated area.
