Polygon c has an area of 7 square units Jennie drew a scaled version of polygon c and labeled it polygon d polygon d has an area of 28 square units what scale factor did jennie use to go from polygon c to polygon d

Respuesta :

Answer:

The scale factor is equal to 2

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 ----> the area of polygon d

y ---> the area of polygon c

so

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

we have

[tex]x=28\ units\^{2}[/tex]

[tex]y=7\ units\^{2}[/tex]

[tex]z^{2}=\frac{28}{7}[/tex]

[tex]z^{2}=4[/tex]

[tex]z=2[/tex]

therefore

The scale factor is equal to 2
