🚀 Features

🟦 Rectangle Class

• Compute area, perimeter, diagonal
• Generate ASCII pictures (get_picture)
• Measure how many shapes fit inside (get_amount_inside)
• Supports dynamic width & height updates
• Clean repr: Rectangle(width=10, height=5)

🟥 Square Class

• Inherits from Rectangle
• Always maintains equal sides
• Setter methods are overridden (set_side, set_width, set_height)
• Clean repr: Square(side=5)

📘 Usage Example

from polygon_calculator import Rectangle, Square

rect = Rectangle(10, 5)
print(rect.get_area())        # 50
print(rect.get_perimeter())   # 30
print(rect.get_diagonal())    # 11.18
print(rect.get_picture())

sq = Square(8)
print(sq.get_area())          # 64
sq.set_side(4)
print(sq.get_diagonal())      # 5.66
print(sq.get_picture())

rect.set_width(16)
rect.set_height(8)
print(rect.get_amount_inside(sq))  # 8
