Question

In a conference hall of a school, 900 students were sitting in such a way that there were as many rows as there were students in a row. How many rows were there?

Answer 1

$\huge\boxed{\underline{\sf{\red{ᴀ}\green{ɴ}\pink{s}\orange{ᴡ}\blue{ᴇ}\pink{ʀ}}}}$

Suppose the number of students in each row of the lecture room = z 

That's why, number of rows = z 

And total students = z²

As per question, z²= 900

Hence, students in each row of the lecture = $30$

Answer 2

Suppose the number of students in each row of the lecture room = z
