Answer: Second option is correct.
Step-by-step explanation:
Since we have given that
Let the original dimension of pentagon be x
So, we have ratio as follow:
[tex]\frac{3}{12}=\frac{x}{8}\\\\3\times 8=12\times x\\\\24=12\times x\\\\x=\frac{24}{12}=2[/tex]
so, Paolo was asked to find the original of an enlarge pentagon.
And she did,
[tex]8x=36\\\\x=4.5[/tex]
so, she made an error when he cross multiplied the proportion.
That's why she got wrong answer.
Hence, Second option is correct.
