Answer: The exponential model for the area would be
.
Step-by-step explanation:
Since we have given that
Initial square miles = 8
It gets tripled in every 4 hours.
So, in every 4 hours, it become 3.
In every 1 hour, it becomes 
So, According to question, an exponential model for the area would be

Hence, the exponential model for the area would be
