Question

The perimeter of a rectangular painting is 316 centimeters. If the length of the painting is 92 centimeters, what is its width?

Answer 1

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
