Let the number of rows be, x.
∴ the number of plants in each rows = x.
Total many contributed by all the students = x × x = x2
Given, x2 = Rs. 2025
x2 = 3 × 3 × 3 × 3 × 5 × 5
⇒ x2 = (3×3)×(3×3)×(5×5)
⇒ x2 = (3×3×5)×(3×3×5)
⇒ x2 = 45 × 45
⇒ x = √45×45
⇒ x = 45
∴ The number of rows = 45 and the number of plants in each rows = 45.
