We want to know how many meters is the perimeter of the poster on Brenna's wall, given that we know that it has a perimeter of 94 centimeters.
We see that we have to do a conversion of units: from centimeters to meters. On this case, we divide by 10 two times, for going to centimeters to decimeters, and then from decimeters to meters. We obtain:
[tex]94\operatorname{cm}=\frac{94}{10}dm=9.4dm=\frac{9.4}{10}m=0.94m[/tex]And this means that the perimeter of the poster on Brenna's wall is 0.94 centimeters.
