Polygon Y has an area of 11 square units. Celia drew a scaled version of Polygon Y using a scale factor of
3 and labeled it Polygon Z.
What is the area of Polygon Z?

Respuesta :

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

[tex]z^{2}=\frac{x}{y}[/tex]

we have

[tex]z=3[/tex]

[tex]y=11\ units^2[/tex]

substitute and solve for x

[tex]3^{2}=\frac{x}{11}[/tex]

[tex]x=9(11)\\x=99\ units^2[/tex]

so

The area of polygon Z is 9 times the area of polygon Y

The area of polygon Z is 99 square units

Answer:

99
