Answer:
square foot per hour
Step-by-step explanation:
The total area covered = 34 square foot
Time taken = 12 hours
This implies that it takes 12 hours to cover 34 square foot.

12 hours ---------------------------------------> 34 square foot
Dividing both sides by 12
--------------------------->
1 hour ---------------------------------------> square foot per hour
The unit rate in square feet per hour is square foot per hour
