9
21
24
48

Explanation:

Step1: Recall area formula

The area formula for a rectangle is $A = L\times W$, where $A$ is area, $L$ is length and $W$ is width. Given $A = 54$ square - inches and $L = 6$ inches, we have the equation $54=6\times W$.

Step2: Solve for width

To find $W$, divide both sides of the equation $54 = 6\times W$ by 6. So, $W=\frac{54}{6}=9$ inches.
