The answer is 8 rows.

Explanation:

It is given that each row contain only 5 circles and there are 40 circles in the array. In order to find the numbers of row, you have to divide the total of circle by the number of circle in each row :

total = 40 circle

each row = 5 circle

5 circles = 1 row

40 circles = x row

x = 40/5

= 8 rows
