Question

1521trees 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?​

Answer 1

Answer:

Let the number of rows be x

So the number of trees are x

$x \times x = 1521 \\ \\ {x}^{2} = 1521 \\ \\ x = \sqrt{1521} \\ \\ x = \sqrt{3 \times 3 \times 13 \times 13} \\ \\ x = 3 \times 13 \\ \\ x = 39$

There are 39 rows and 39 trees.
