# Still stuck on this

Square.cs
```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;
}

public void Scale(double factor)
{
SideLength *= factor;
}
}
}
```
Polygon.cs
```namespace Treehouse.CodeChallenges
{
class Polygon
{
public int NumSides { get; private set; }

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

Just kidding. I was thinking about another topic. I'm still stuck on this though.

## It doesn't look like you've written any code yet.

This challenge is about using the syntax for expression-bodied members, also called the "arrow" notation. Without changing what they do, you'll convert a property and a method from the classic syntax to the "arrow" notation.

What you need to do here is very close to the examples given in the previous video. You might want to give it another look.

The previous topic is what should be read. I just reposted this so I can get a proper answer.

What do you mean by "previous topic"? Oh, now that I think about it, I helped you with this same issue before on this other question, but since you did not reply to my second answer I expected that you had already solved the challenge and moved on.

What did you do after the second hint? You had already solved task 1 before .. but your code here looks like you haven't started yet.

Hi there, M. Brown! I took a look at the other question you posed as linked by Steven Parker and from my perspective it seems like you've already gotten several detailed responses regarding the nature of the problem. In the code listed here, it doesn't appear as though you've written anything yet, but I'm sure you've written something that just isn't passing. I'd be very curious to know what that is so we might help you understand anything you might be missing.

Also, could you please elaborate on what you consider a "proper answer"? If you mean an explicit answer with code that you can copy and paste, you should be aware that Treehouse generally discourages giving straight out copy/paste answers when hints and advice will generally suffice.

Until we see your code, I might recommend reviewing 1:29 to 1:50 of the preceding video.

I look forward to seeing your code!
