The teacher wants to arrange the students in equal number of rows and columns.
She also wants to have 9 rows. So, there should be 9 columns so as to fulfill her requirement.
Hence, there are 9 rows and 9 columns and the number of students = 9 x 9 = 81.
Answer:
The number of students required for the performance = 81 students
Step-by-step explanation:
The teacher wants to arrange the students in equal number of rows and columns.

So, the matrix must be square matrix of 9 × 9.
The number of students required for the performance = 9 × 9 = 81 students
Herewith I have attached the array of students.
