Answer: 60
Step-by-step explanation:
Let the side lengths of the rectangular pan be m and n. It follows that (m-2)  (n-2)=  
 
So, since haf of the brownie pieces are in the interior. This gives 2 (m-2) (n-2) =mn 
mn- 2m - 2n- 4 = 0 
Then Adding 8 to both sides and applying, we obtain (m-2) (n-2) =8 
Since now, m and n are both positive, we obtain (m,n) = (5,12), (6,8) (up to ordering). By inspection, 5. 12 = 60 
which maximizes the number of brownies in total which is the greatest number.
Hope that helped! =)
