Solution

Length of pole $= 18 m$
Percentage of pole which is painted green $= 20 %$
Percentage of pole which is painted yellow $= 45 %$
and remaining pole $= 100 - (20 + 45) = 35 %$
and it is painted red
Length of pole which is painted red
$= 35 %$ of $18 m = \frac{35}{100} \times 18$
$= \frac{63}{10}$
$= 6.3 m$
