~please only answer if you know for sure~

Answer 1

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

Make a proprtion of the sides.


`\sf{ (WX)/(AB) = (ZW)/(DA) }`

Plug in the numbers


`\sf{ (6)/(24) = (ZW)/(18) }`

Cross multiply


`\sf{ 6* 18=ZW * 24`

And then solve for ZW


`\sf{ZW = 4.5}`

So our final answer is


`\boxed{\bf{4.5~centimeters}}`

Hope that helps :P
