Answer 2

Answer:

The number of seats in each row are 30.

Step-by-step explanation:

Suppose there are 'x' seats in each row in the hall.

Number of rows = 2 × the number of seats in each row

                           =  2 × x = 2x

Total number of seats = Number of rows × number of seats in one row

                                     = (2x) × (x) = 2x²

• It is mentioned in the question that, total number of seats in the hall is 1800.

       So we can write,  2x² = 1800

                                       x² = $\frac{1800}{2}$ = 900

                                       x² = (30)² or (-30)²

       The value of x can be 30 or -30. But here x represents the number of seats, which can not be a negative number.

       So, the possible value of x is 30.

∴ The number of seats in each row are 30.
