Question

7921 soldiers sat in an auditorium in such a way that there are as many soldiers in a row as there are rows in the auditorium. how many rows are there in the auditorium ?

Answer 1

Answer:

Number of rows in the auditorium = 89

Number of rows in the auditorium = 89Number of soldiers seated in each row = 89

Step-by-step explanation:

Let the number of rows in a auditorium = x

Number of soldiers seated in each row = x

Total number of soldiers in the auditorium = x × x

= x²

According to the problem , given

$x^{2} = 7921$

$\implies x = \sqrt{7921}\\=\sqrt{89 \times 89 }\\=89$

Therefore,

Number of rows in the auditorium = 89

Number of soldiers seated in each row = 89
