Question

In an auditorium, the number of rows is equal to the number of chairs in each row. If the capacity of the auditorium is 7921, find the number of chairs in each row.

Answer 1

In an auditorium no. of rows is 'X'  No. of chairs is given in each row so no of rows is X No of chairs =  7921

X.X=7921

X²= 7921

X= √7921

 

X=89

∴ No of rows =89

No of chairs =89

∴ No. of chairs in each row =89

Answer 2

Answer:

89

Step-by-step explanation:

Number of rows × number of columns = 7921

According to the question,

Number of rows = numberos columns, then, let number of rows be x and so column,

x × x = 7921

x² = 7921

x = √7921

x = 89

Therefore, the number of chairs in one row = 89.
