2025 plants are to be planted in a garden in such a way that each row contains as many plants as the number of rows. Find the number of rows and the number of plants in each row.
Solution
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.
