ANSWER:

66 centimeters

Explanation:

The perimeter is defined as follows:


p=2\cdot W+2\cdot L

We know the value of the perimeter and the value of the length, we replace and solve for the width, just like this:


\begin{gathered} 316=2\cdot W+2\cdot92 \\ 316=2W+184 \\ 2W=316-184 \\ W=(132)/(2) \\ W=66 \end{gathered}

Therefore, the width is 66 centimeters
