Explanation:

Step1: Find area of first rectangle

The first rectangle has length \( 9 \) and width \( 7a \). The area of a rectangle is \( \text{length} \times \text{width} \), so \( 9\times7a = 63a \).

Step2: Find area of second rectangle

The second rectangle has length \( 9 \) and width \( - 5 \). Using the area formula, \( 9\times(-5)=-45 \).

Step3: Combine the areas

To find \( 9(7a - 5) \), we add the areas of the two rectangles: \( 63a+(-45)=63a - 45 \).

Answer:

\( 63a - 45 \)
