In a park, 784 plants are arranged so that number of plants in a row is same as the number of rows. The number of plants in each row is—

If the number of plants in each row equals the number of rows, then total plants = (number per row)². So (number per row)² = 784. Taking square root: √784 = 28. Therefore, there are 28 plants in each row and 28 rows.
