number of rows and columns of seats should be equal. If there are total 1849
seats then find out the number of rows and column.​

Answer 1

Answer: 43

Step-by-step explanation:

Let number of rows = Number of columns = n

Total number of seats = 1849

==> n^2 = 1849

==> n = √(1849) = 43

Answer 2

Answer:

The number of rows = The number of columns  = 43

Step-by-step explanation:

Given,

The number of rows and columns of seats in a cinema hall are equal

Total number of seats = 1849

To find,

The number of rows and columns

Solution:

Let 'x' be the number of rows of seats in the cinema hall

Since the number of rows and columns are equal, we have the number of columns of seats = x

The total number of seats = number of rows × number of columns

= x × x

= x²

Since the total number of seats = 1849, we have

x² = 1849

x = $\sqrt{1849} =$$\sqrt{43X43}$ = 43

x = 43

∴ The number of rows = The number of columns  = 43
