1521 trees are planted in a garden in such a way that there are as man

1.	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.
Answer» Let the no. of trees planted in a garden for each row = x say. No. of rows in the garden = x ∴ Total no. of trees in the garden = x × x = x² According to the sum x² = 1521 x = \(\sqrt{1521}\) = \(\sqrt{39\,\times\,39}\) = 39 ∴ No. of trees for each row = 39 No. of rows in the garden = 39

Answer»

Let the no. of trees planted in a garden for each row = x say.

No. of rows in the garden = x

∴ Total no. of trees in the garden = x × x = x²

According to the sum x² = 1521

x = \(\sqrt{1521}\) = \(\sqrt{39\,\times\,39}\) = 39

∴ No. of trees for each row = 39

No. of rows in the garden = 39
