It is given that in the garden, each row contains as many plants as the number of rows.

Hence, Number of rows = Number of plants in each row Total number of plants = Number of rows × Number of plants in each row

Number of rows × Number of plants in each row = 2025

(Number of rows)^{2} = 2025

**Number of rows** = √2025

2025 = 5 x 5 x 3 x 3 x 3 x 3

∴ √2025 = 5 x 3 x 3 = 45

Thus, the number of rows and the number of plants in each row is 45.
