Answer

67.5 feet

Work Step by Step

The two flies are similar shapes. This means that all of the sides are proportional. We will call x the side that we want to find (the wingspan of the long fly). Thus, we set up the equation: $x/.5=27/.2$. We multiply both sides of the equation by .5 to obtain that $x=67.5$.
