CPM Homework Help : MC1 Problem 8-53

Hint:

If we use each ratio as new/original, then the example below shows the lengths of a new diagram that would have sides that are five times as long as the original.

Hint (a):

If you choose to use a ratio of new/original, you will need to enlarge the figure. Use the example.
Can you draw your own diagram?

Hint (b):

$\text{For part (b), the new diagram will be }\frac{2}{3}\text{ the size of the original.}$

$\text{Since all sides of the figure are 3 units or 6 units, it may help to know that }\frac{2}{3} \text{ of 3 is 2 and }\frac{2}{3}\text{ of 6 is 4.}$

Can you draw the new figure?
