Question

i have no idea how to make it in one line
```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;
    }
}
}
```

:point_right: If you're totally lost, re-watch the Expression Bodied Members (https://teamtreehouse.com/library/c-objects/encapsulation-with-properties/expression-bodied-members) video.
There's a good example of converting a computed property get into a single line at about time index 01:26.
It's basically just removing the "get", "return", and braces and adding the ("=>") symbol.
