Refactor using Solid Principles

Question

I have this code , i wanted to modify it using SOLID principles where all can i edit it please suggest

class Program
{
static void Main(string[] args)
{
List<Figure> figureList = new List<Figure>();
Figure rectangle = new Figure()
{
Height = 3,
Width = 4,
Type = ShapeType.Rectangle
};
figureList.Add(rectangle);
Figure square = new Figure()
{
Height = 4,
Type = ShapeType.Square
};
figureList.Add(square);
Figure circle = new Figure()
{
Radius = 3.5,
Type = ShapeType.Circle
};
figureList.Add(circle);
foreach (Figure figure in figureList)
{
Console.WriteLine(figure.CalculateArea());
figure.Save();
}
}
}
public class Figure
{
public double Height { get; set; }
public double Width { get; set; }
public double Radius { get; set; }
public ShapeType Type { get; set; }
public void Save()
{
if (Type == ShapeType.Circle)
throw new Exception("Circle cannot be saved!");
//save the object to a file
using (Stream stream = File.Open("saveFile.bin", FileMode.OpenOrCreate))
{
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, this);
}
}
public double CalculateArea()
{
try
{
if (Type == ShapeType.Rectangle)
{
return Height * Width;
}
else if (Type == ShapeType.Square)
{
return Height * Height;
}
else if (Type == ShapeType.Circle)
{
return Radius * Radius * Math.PI;
}
}
catch (Exception e)
{
if (e is ArgumentNullException)
{
//log to a file
System.IO.File.WriteAllText("log.txt", e.ToString());
}
else if (e is ArgumentException)
{
//log to console
Console.WriteLine(e.ToString());
}
}
return 0;
}
}
public enum ShapeType
{
Rectangle,
Circle,
Square
}
