makkiz [27]

Hi there! :)

Answer:

$\huge\boxed{\frac{9cm}{8cm}}$

We can disregard the units temporarily to create a ratio for 4.5 to 4:

4.5 is not a whole number- we can convert this number in the ratio to a whole number by multiplying both numbers by 2:

2 · (4.5 : 4) = 9 : 8

Express as a fraction:

$9cm : 8cm = \frac{9cm}{8cm}$

Step-By-Step explanation:

You can take the x and y values of the points and use them on the opposite axis, depending on how many times you would have to use them on the opposite axis you can determine how much rotation is needed (Every time you use the points on the opposite axis it is equivalent to 90 degrees).
