Respuesta :

the scale factor is 1.5

Answer:

The scale factor is equal to [tex]1.5[/tex]

Step-by-step explanation:

we know that

If rectangle JKLM is similar to rectangle WXYZ

then

the ratio of their corresponding sides is equal and is called the scale factor

so

In this problem

[tex]\frac{ZW}{JM} =\frac{WX}{JK}[/tex]

In this problem we have

[tex]ZW=13.5\ cm[/tex]

[tex]JM=9\ cm[/tex]

[tex]WX=18\ cm[/tex]

[tex]JK=12\ cm[/tex]

Substitute

[tex]\frac{13.5}{9} =\frac{18}{12}[/tex]

[tex]1.5=1.5[/tex] -----> is true

The rectangles are similar

The scale factor is equal to [tex]1.5[/tex]
