Let's see... we have a desk that's 25 in. long and 18 in. wide, and another geometrically similar desk that's 60 in. long and x in. wide. Now, the special property of similar shapes is that the ratios of their sides will always be the same. Doing that gives us \({25\over 60}={18\over x}\), which, using basic algebra gets us: 

 

\(25x=18*60=1080\)

\(x={1080\over 25}=43.2\) inches, which is the width of the second desk.
