From the question it is given that,

Total number of students were sitting in a lecture room = 8649

Let us assume the number of students in each row be ‘a’

Then,

Total number of students = a × a

8649 = a^2

By taking square root on both sides,

a = √(8649)

a = √(93 × 93)

a = √(93)^2

a = 93

∴ The number of students in each row is 93.
