Answer 2

Answer:

Total students in a row = 5 students

Step-by-step explanation:

Let the Number of rows and number of columns = x

Thus, the total students arranged in the group is x × x = x² ---- 1

Now, while arranging, out 30 students, 5 students were left off.

So, the total students arranged in the group = 30 - 5

= 25

Thus,

From eq.1 we get,

x² = 25

x = √25

x = +5 or -5

We can omit the negative value as the number of a certain things can't be negative.

Thus,

Total students in a row and a column = x = 5

Hence,

Total students in a row = 5 students
