Answer:165
First, we have to find out what is 6 in by 9 in. This can be solved through multiplication. 6 x 9 =54.
Next, since we are trying to find how many fits in 35,640 sq in,we have to first find out how many is in 35,640 inches. 35,640÷54 is 660.
We only found how much was in by inches. Now we have to find by square inches. A square is 4 sides, so 660÷4. This gives 165.
I hope this helped you out and was the answer!
