There are 625 plants arranged in as many rows as there are plants in each row. The number of plants in each row would be ______?

None of these

Let's say the number of plants in each row is x.

Since there are as many rows as there are plants in each row, the total number of plants is x * x = x².

Given that the total number of plants is 625:

x² = 625

x = √625

x = 25
