The number of rectangles formed in the figure corresponds to the perimeter of the shape.
1st rectangle: Perimeter = 4 + 4 + 7 + 7 = 22
2nd rectangle: Perimeter = 4 + 4 + 7 + 4 + 7 + 4 = 30
3rd rectangle: Perimeter = 4 + 4 + 7 + 4 + 4 + 7 + 4 + 4 = 34
Therefore, as the number of rectangles increases, the perimeter of the figure also increases.
In the diagram below, what is the relationship between the number of rectangles and the
perimeter of the figure they form?
1st rectangle is 4 and 7
2nd rectangles is 4 and 4 and 7
3rd rectangles are 4 and 4 and 4 and 7
