12 in
area = 84 in²

Explanation:

Step1: Recall the area formula of a rectangle

The area formula of a rectangle is \(A = l\times w\), where \(A\) is the area, \(l\) is the length, and \(w\) is the width.

Step2: Solve for the width

We know that \(A = 84\space in^{2}\) and \(l=12\space in\). Rearranging the formula for \(w\), we get \(w=\frac{A}{l}\).
Substitute the values: \(w = \frac{84}{12}\)
\(w = 7.0\space in\)

Answer:

\(7.0\space in\)
