Answer:
[tex]JK=2.25\ units[/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{JK}{ST}=\frac{KL}{TU}[/tex]
substitute the given value and solve for JK
[tex]\frac{JK}{1.5}=\frac{6}{4}[/tex]
[tex]JK=(1.5)\frac{6}{4}[/tex]
[tex]JK=2.25\ units[/tex]
