Answer: There will be 3 rows with 3 photos.
Step-by-step explanation:
Since we have given that
Number of photos to be arranged by Amir on a bulletin board = 9
According to question, we have given that each row contains the same number of photos.
Let the number of rows be x
So, the number of photos also be x
So, our equation becomes
\(x^2=9\\\\x=\sqrt{9}\\\\x=3\)
So, there will be 3 rows with 3 photos.
