Answer:
Polygon Y's area is one ninth (1/9) of Polygon X's area
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
In this problem
Let
z-----> the scale factor
a-----> Polygon Y's area
b----> Polygon X's area

we have

substitute



therefore
Polygon Y's area is one ninth (1/9) of Polygon X's area
All you have to do is multiply them all.
3*3*4*2=72
