I don't understand that question what actually ask for me?

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

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

        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 doesn't look like you've started writing any code yet. Let's break the task down into parts:

  • add a new property to the "Square" class
  • give the property the name "Area"
  • it will be a computed property so it will need a "get" method
  • the "get" method will return the result of a calculation
  • the calculation will implement the standard formula for the area of a square
  • the calculation will use the value of "SideLength"

You might be able to get it now, or at least make a start at writing the code. If you're still stuck, perhaps you can identify a particular part now that's giving you trouble.
