Answer:

$\huge\boxed{width=12cm}$

Step-by-step explanation:

$l-length\\w-width\\P-perimeter$

The formula of perimeter of the rectangle:

$P=2l+2w=2(l+w)$

Substitute:

$l=6w\\\\P=168cm$

$168=2(6w+w)\\168=2(7w)\\168=14w\qquad|\text{divide both sides by 14}\\\\\dfrac{168}{14}=\dfrac{14w}{14}\\\\12=w\Rightarrow w=12(cm)$
