Question

in the hall the number of rows is equal to the number of chairs in each row if the capacity of the hall is 1296 find the number of chairs in each row​

Answer 1

Answer:

36

Step-by-step explanation:

take simple example first of 3*3 rows and colums example

then number of chairs =multiplication of rows and colums=9

So,as rows and clums are given equal take it as X

So X^2=1296

X=36

Answer 2

Given:

In the hall, the number of rows is equal to the number of chairs in each row and the capacity of the hall is 1296.

To find:

The number of chairs in each row.

Solution:

As given, we have,

In a hall, the number of rows = the number of chairs in each row.

Let the number of rows in the hall be x.

So, the number of chairs in each row is also x.

Thus,

the capacity of the hall

$= {x}^{2}$

Also given,

the capacity of the hall = 1296

So,

${x}^{2} = 1296$

on taking square root on both sides, we get

$x = + 36 \: and \: - 36$

Neglecting x = -36 as the number of rows or chairs cannot be negative,

So, the number of chairs in each row is 36.
