A concert hall has 10 seats in the first row and 12 seats in the second row. If each row has 2 more seats than the previous row, and there are 30 rows of seats, how many seats are in the entire concert hall? PLEASE HELP

final answer is : )

i think c. but don't trust it.

step-by-step explanation:

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
