Explanation:

Step1: Identify the formula for the area of a rectangle

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

Step2: Substitute the given values into the formula

Given \(l = 13\) in and \(w = 9\) in. Then \(A=13\times9\).

Step3: Calculate the product

\(13\times9=(10 + 3)\times9=10\times9+3\times9 = 90+27=117\)

Answer:

\(117\ \text{in}^2\)
