A hall has a capacity of 2704 seats. If the number of rows is equal to the number of seats in each row, then find the number of seats in each row.

Given:

Let the number of seats in each row = y


number of seats in a row = the number of rows = y


Hence, total seats = y × y


Acc. To given condition:


Y2 = 2704


⇒ y2 = 52 × 52


⇒ y2 = 522


⇒ y = 52


Hence, the number of seats in each row = 52
