Question

Polygon Y is a scaled copy of Polygon X using a scale factor of 1/3 Polygon Y's area is what fraction of Polygon X's area?

Answer 1

Answer:

1/9. Because the area is measured in units squared, then you have to square 1/3 which is 19th.

Step-by-step explanation:

The area is measured in squared units. You have to square 1/3 which is 1/9. $\frac{1}{3} ^2= \frac{1}{3} (\frac{1}{3})$

Answer 2

Answer:

1/9

Step-by-step explanation:

SideY/sideX = ⅓

AreaY/AreaX = (sideY/sideX)²

= (⅓)²

AreaY/AreaX = 1/9
