Answer:
The side lengths of the image after the dilation = 13.5 cm and 20.25cm
Step-by-step explanation:
A rectangle has side lengths 6 cm and 9 cm. What would the side lengths of the image be after a dilation of 2.25? Explain your reasoning.
Dilation can also be referred to as scale factor
6cm × 2.25 = 13.5 cm
9 cm × 2.25 = 20.25 cm
The side lengths of the image after the dilation = 13.5 cm and 20.25cm

Use Pythagorean's Theorem to find the length of x.
so
and
. We can simplify that radicand down into a perfect square times a prime number, and that is
. 4 is a perfect square that can be pulled out as a 2, so the length of x is
, the choice on the top right.
