Answer:
A. 9
Step-by-step explanation:
The scale factor = 3, meaning that you have to multiply the og shapes side lengths by 3 in order to get the new shapes side length.
We know that 10 × 3 = 30, so now we have to find what the width of the og rectangle will be.
27 / 3 = 9, so ? = 9.
To check your answer, you can multiply 9 × 3 = 27. So 9 is the missing width.
? = 9
