A Sequence of Rectangles
Write the information from page 567 to fill in the perimeter and area for these rectangles:
Perimeter | Area | |
---|---|---|
All sides × 2 | ||
All sides × 4 | ||
All sides × 3 | ||
All sides × 6 |
8 Consider these pairs of rectangles where the dimensions are doubled (rectangles with all sides × 2 and all sides × 4, or those with all sides × 3 and all sides × 6). What happens to the perimeter when you double each of the dimensions of a rectangle?
9 Consider the same pairs of rectangles as above. What happens to the area?
10 Did perimeter and area of rectangles change in the same way it did for squares? Explain your thinking.
