2,097 PointsStuck in "Computed Properties" task
I have been stuck with this problem for a couple days. Any help is appreciated.
The problem is I don't know what I am doing wrong and it keeps throwing a error saying "Did you make Square.Area readonly with no setter".
namespace Treehouse.CodeChallenges
{
class Square : Polygon
{
public double SideLength { get; private set; }
public double Area
{
get
{
return Area;
}
set
{
Area = SideLength * SideLength;
}
}
public Square(double sideLength) : base(4)
{
SideLength = sideLength;
}
}
}
namespace Treehouse.CodeChallenges
{
public class Polygon
{
public int NumSides { get; private set; }
public Polygon(int numSides)
{
NumSides = numSides;
}
}
}

Treehouse Guest TeacherHello Pedro,
Since we only need to return a value from the computed property, you only need the "get" part of the property. This will make the property readonly because we don't provide a setter.
In the get block, you'll want to return SideLength * SideLength like this.
public double Area
{
get
{
return SideLength * SideLength;
}
}
I hope this helps.
