Polygon y is a scaled copy of polygon x using a scale factor of \dfrac13 3 1 start fraction, 1, divided by, 3, end fraction. polygon y's area is what fraction of polygon xxx's area?

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
