Courses Plus Student 1,073 PointsI'm stuck!
I think I didn't understand really well what is a computed property and because of that I have no idea what to do here, can someone please help me!
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;
}
}
}

230,230 PointsWell, you have "SideLength" as an example of an auto property. For a computed property, the syntax will be similar but the "get" will have a body with code in it and the "set" can be omitted.
For the Area, the body code of the "get" can use "SideLength" to calculate the area and return it.
Give it a shot, and if you still have trouble, show the code you have for it so far.
