Answer:
536 cars can park along one side of this parking lot.
Explanation:
First, divide the parking lot's area by 2 to have an even length and width (since the parking lot is a square, each side haas the same length).
9640 ÷ 2 = 4820 ft
Now divide 4820 by 9 (the width of each parking space) to see how many parking spaces, cars, can fit into one side
4820 ÷ 9 = 535.56 ≈ 536 parking spaces for cars
536 cars can park along one side of the parking lot.
