C# C# Objects Encapsulation with Properties Computed Properties

I am lost on how to do it

I am lost on where I need to create the computed property

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

        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;
        }
    }
}

It's quite a simple. Just add a property in Square.cs If it helps you don't forget to upvote.

        public double Area 
        { 
            get
            {
                return SideLength * SideLength;
            }
        }

Full code looks like this.

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

        public double Area 
        { 
            get
            {
                return SideLength * SideLength;
            }
        }       

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

Thank you
