<｜begin▁of▁sentence｜>### Instruction:
As a sound engineer, imagine you're working on a film project where you're responsible for adjusting the volume levels of different audio tracks to ensure a balanced sound mix. Now, suppose you have a specific track representing the dialogue, and you need to adjust its volume level. How would you go about changing the volume level of the dialogue track using your mixing console, and then how would you retrieve the new volume level reading from the console?
### Response:
from matplotlib.patches import Rectangle

# Create a rectangle with the given width
rect = Rectangle((0, 0), width=10, height=5)

# Set the width of the rectangle to 20
rect.set_width(20)

# Get the new width of the rectangle
new_width = rect.get_width()

print('The new width of the rectangle is:', new_width)
