Answer:

Choice A

Step-by-step explanation:

When you have two shapes that are similar their sides are always proportional. So all we have to do is set up a proportion.

[tex]\frac{18}{4.5}=\frac{x}{1.5}[/tex]

Now we cross multiply and solve

[tex]27=4.5x\\x=6[/tex]

And that's it x equals 6 feet.
