1225 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.

Answer :

Let the number of rows be x

Therefore,


The number of plants in each row is also x


Hence,


Total number of plants = (x × x) = x2 = 1225


x2 = 1225 = 5 × 5 × 7 × 7


x = = 5 × 7 = 35


Thus,


The total number of rows is 35 and the number of plants in each row is also 35
