1521 trees are planted in a garden in such a way that there are as many trees in each row as there are rows in the garden. Find the number of rows and number of trees in each row.

Given, 1521 trees are planted in a garden. We need to find out number of rows and number of trees.

Let us assume the number of trees in each row = x.

Since, we know that number of trees in each row = number of rows in the garden.

Total number of trees planted in a garden = x × x = x²

Calculate x value.

∴ x² = 1521

Calculate, prime factors for 1521.

We know from pairing the factors

⇒ x² = (3 × 3) × (13 × 13)

⇒ x² = 3 × 13

⇒X = 39

Hence, the number of trees in each row is 39 and number of rows in the garden is also 39.
