The ratio of the acutal plane is:
[tex]27\text{ ft long:18 ft wingspan}[/tex]
By using proportions, we can find the answer as follows:
[tex]\frac{27ft\text{ long}}{18ft\text{ wingspan}}=\frac{13.5in\text{ long}}{x}[/tex]
Where x is the measure of the wingspan, solving for x we obtain:
[tex]\begin{gathered} x=\frac{13.5in\times18ft}{27ft} \\ x=9in \end{gathered}[/tex]
The wingspan will be 9 in.
