Answer 2

Answer: Option 'C' is correct.

Explanation:

Since we have given that

Polygon X is similar to polygon.

And Polygon X is three times the size of polygon Y.

So, it becomes,

`\frac{\text{Perimeter of polygon X}}{\text{Perimeter of polygon Y}}=(3)/(1)\\\\(81)/(x)=(3)/(1)\\\\x=(81)/(3)\\\\x=27`

Hence, perimeter of polygon Y is 27.

Therefore, Option 'C' is correct.
