Question

A hall has a capacity of 3200 seats. If the number of rows is twice the number of seats in each row, then find the number of seats in each row

Answer 1

Answer:

Step-by-step explanation:

Let the number of seats in each row be x.

So the number of rows is 2x

So the total number of seats in the hall=2x×x

=2x²

ATQ, 2x²=3200

=>. x²=3200/2=1600

=>. x=√1600=40

Thus the number of seats in each row is 40.

Hope you got it.
