Answer:
The area of polygon Z is 99 square units
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
Let
z ----> the scale factor
x ----> area of polygon Z
y ----> area of polygon Y
we have
substitute and solve for x
so
The area of polygon Z is 9 times the area of polygon Y
The area of polygon Z is 99 square units
