Solution
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.
