Answer:
The scale factor is [tex]\frac{9}{7}[/tex]
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
so
[tex]\frac{18}{14}=\frac{27}{21}=\frac{9}{7}[/tex]
therefore
The scale factor is 9/7
Find the value of x
The value of x is equal to
[tex]\frac{x}{28}=\frac{9}{7}[/tex]
[tex]x=28(\frac{9}{7})=36\ units[/tex]
