In the town hall meeting room, i sit in the fourth row from the front, which is also the twelfth row front the back. each row has 14 seats. how many people can be seated in the meeting room? ( explain)

There are 210 people can be seated in the meeting room

Step-by-step explanation:

* Lets explain how to solve the problem

- He sits in the fourth row from the front

- He sits in the twelfth row front the back

∴ His row is the 4th from the front and 12th from the back

- His row counted twice one from front and one from the back

- That means there are 3 rows front of his row and 11 rows back of

 his row

∴ The number of rows in the meeting room = 11 + 3 + 1 = 15 rows

  OR  (12 + 4 - 1 = 15)

- There are 14 seats in each row

∵ Each row has 14 seats

- To calculate the number of seats in the meeting room multiply

  the number of seats in each row by the numbers of the rows in

  the room

∴ The number of seats in the meeting room = 14 × 15 = 210 seats

* There are 210 people can be seated in the meeting room
