Explanation:

Step1: Recall the formula for the area of a rectangle

The formula for the area of a rectangle is \(A = \text{width}\times\text{length}\). Given \(A=9x^{5}-36x\) and \(\text{width} = 9x\). We need to find \(\text{length}\), so \(\text{length}=\frac{A}{\text{width}}\).

Step2: Perform the polynomial division
