Question

7 mi, 9 mi (with a rectangle diagram)

Explanation:

Step1: Identify the shape and formula

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

Step2: Substitute the values

Here, the length \( l = 9 \) mi and the width \( w = 7 \) mi. Substituting these values into the formula, we get \( A = 9 \times 7 \).

Step3: Calculate the product

\( 9 \times 7 = 63 \).

Answer:

The area of the rectangle is 63 square miles.
