. A movie theater has two rooms. Room A has 7 rows of seats with 14 seats in each row. Room B has three times as many seats as room A. How many seats are there in both rooms?

Number of seats in Room A = 98 seats

Number of seats in Room B = 294 seats

Total number of seats for both Room A and B = 392 seats

Step-by-step explanation:

From the above question, we are told that :

A movie theater has two rooms.

Room A has 7 rows of seats with 14 seats in each row.

Hence, the total number of seats in Room A = Number of rows × Number of seats in each row

= 7 × 14 seats

= 98 seats

Room B has three times as many seats as room A.

Room B = 3 × Room A

= 3 × 98 seats

= 294 seats

How many seats are there in both rooms?

Number of seats in Room A = 98 seats

Number of seats in Room B = 294 seats

Total number of seats for both Room A and B

= 98+ 294

= 392 seats
