Answer 1

Answer:

90

Explanation:

8175-75= 8100 which makes a perfect square.

8100= 90*90, thus total 90 rows and 90 columns are there.

no.of students in each row= 8100/90= 90

Answer 2

Given,

total number of students = 8175

number of students out of the rows = 75

To find,

number of students in each row

Solution,

It is given that 75 students did not stand in rows out of the total number of students.

Therefore the number of students standing in rows is,

Students in rows = 8175 - 75

Students in rows = 8100

The number of students in each row can be found by the square root of 8100.

No. of students in each row = √8100

No. of students in each row = 90 students

Therefore the number of students in each row is 90.
