Question

A farmer has 1500 mango saplings. He wants to plant these in such a way that the number of rows
and the number of columns remain same. Find the minimum number of plants he needs more to​

Answer 1

Answer:

He needs 21 more

Step-by-step explanation:

Let no. of rows = no. of columns = x

Area = x²

Area = No. of saplings

x² = 1500

x = √1500, which is not possible

The nearest perfect square = 1521 ( square root 39)

He needs = 1521 - 1500 = 21

Therefore he needs 21 more saplings
