please answer it very urgent​

Answer 1

Answer:

42 chairs

Step-by-step explanation:

Let No. of chairs in 1 row = No. of rows = x

Total no. of chairs=No. of chairs in 1 row x No. of rows

                             =x*x = x² = 1764

=>x=$\sqrt{1764}$

     =42 chairs

Hence, No. of chairs in 1 row=42 chairs

Answer 2

Answer :-

The number of chairs in each row is 42.

Explanation :-

Given :

• Number of rows = Number of chairs
• Capacity of the star - 1764

To find :

No. of chairs in each row

Solution :

Let the no. of chairs in each row be 'x'

Since, the no. of chairs and no. of rows are same, the no. of rows will also be 'x'

According to question,

=> No. of chairs × No. of rows = Capacity of the stadium

=> x × x = 1764

=> x² = 1764

=> x = √1764

=> x = √2 × 2 × 3 × 3 × 7 × 7

=> x = 2 × 3 × 7

.°. x = 42

Hence, the no. of chairs in each row is 42 respectively.
