It is given that the number of rows and the number of columns are the same.

Let a number of rows or number of columns be x.

The number of plants required  =  x^2

The gardener has 1000 plants.

We need to find a perfect square just greater than 1000.

We know,            31^2 = 961          and         32^2 = 1024

So the minimum plants needed by gardener = 1024 - 1000 = 24 plants.
