ZW and DA are similar sides
WX and AB are similar sides.

Make a proprtion of the sides.

[tex]\sf{ \frac{WX}{AB} = \frac{ZW}{DA} }[/tex]

Plug in the numbers

[tex]\sf{ \frac{6}{24} = \frac{ZW}{18} }[/tex]

Cross multiply

[tex]\sf{ 6\times 18=ZW \times 24[/tex]

And then solve for ZW

[tex]\sf{ZW = 4.5}[/tex]

So our final answer is 

[tex]\boxed{\bf{4.5~centimeters}}[/tex]

Hope that helps :P
