In the diagram below, what is the relationship between the number of rectangles and the perimeter of the figure they form?

Without a diagram provided, it is difficult to determine the exact relationship between the number of rectangles and the perimeter of the figure they form. However, in general, as the number of rectangles increases, the perimeter of the figure formed by them may also increase. This is because each additional rectangle adds additional sides to the figure, which increases the total length of the perimeter.
