Answer
$5\;ft$
Work Step by Step
Let the length of the flag is $l=9.5\;ft$.
and the width of the flag is $w$.
Length $=1.9$ times its width.
The equation is
$\Rightarrow l=1.9w$
Substitute the value of $l$.
$\Rightarrow 9.5\; ft=1.9w$
Divide each side by $1.9$.
$\Rightarrow \frac{9.5\; ft}{1.9}=\frac{1.9w}{1.9}$
Simplify.
$\Rightarrow 5\; ft=w$
Hence, the width of the flag is $5\;ft$.
