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
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.
