Given
The ratio of the length of an airplane wing to its width is 8 : 1
length of the wing = 31.8 m
Find
how wide must it be?
Explanation
as we have given the ration of length to width = 8 : 1
let width be x m
so ,
[tex]\begin{gathered} \frac{8}{1}=\frac{31.8}{x} \\ 8x=31.8 \\ x=3.975 \end{gathered}[/tex]Final Answer
Hence , the airplane wing must be 3.98 meters wide.
