Question

1525students are to be arranged in a rows to form a square.find the number of the students in each row and the number that are left out.​

Answer 1

Answer:

No. of students in each row=39

No. of students left out=4

Step-by-step explanation:

To form a square,

No. of rows (x)=No. of students in each row

Then

Total no. of students in the square formed is=x^2

Now,

${x}^{2} \leqslant 1525$

$x \leqslant \sqrt{1525}$

$x \leqslant 39.0512484$

The closest whole no. less than 39.0512484 is 39.

Then the no. of students in a square formed by 39 rows and 39 column (or no. of students in each row)

= 39^2

=1521

Thus no. of students left out is= 1525-1521=4
