Question

A gardener planted 1521 trees in rows such that the number of rows was equal to the number of plants in each row find the number of rows. ​

Answer 1

number of rows=x

number of plants=y

x=y

xy=1521

x^2=1521

taking sq. root on both sides

x=39

y=39

Hence, number of rows is equal to the number of plants = 39.
