Explanation:

• For the wire around the window: The perimeter measures the total length around a shape. Since the wire is placed around the window (i.e., along its boundary), we use the perimeter.
• For the glass in the window: The area measures the amount of surface within a shape. Glass fills the surface of the window, so we use the area.

Answer:
