Question

8649 students were sitting in a lecture room in such a manner that there were as many students in the row as there were rows in the lecture room. How many students were there in each row of the lecture room?

Answer 1

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

Suppose number of students in each row be ‘x’

According to the question,

Total number of students = x × x

8649 = x²

By taking square root on both side,

x = `sqrt(8649)`

x = `sqrt(93 xx 93)`

x = `sqrt(93^2)`

x = 93

Hence, the number of students in each row is 93.
