I dont understand this code challenge.
namespace Treehouse.CodeChallenges
{
class Square : Polygon
{
public double SideLength { get; private set; }
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;
}
}
}

13,360 PointsThe code challenge is about computed properties (auto properties). The goal is to create a property, that automatically return a computed value when called.
In this specific case you want to create a property named Area that returns the computed area of the square when called. This can be used by specifying a calculation in the getter of the Area property:
public double Area
{
get {
return SideLength*SideLength;
}
}
When calling Square.Area the getter will automatically calculate the area from SideLength, and the area will always use the latest value of SideLength.
