Question

A farmer has 2000 plants. 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 for this.
in the center of the following decimal numbers​

Answer 1

25

the number of rows and the number of columns are equal.

let the no. of row be x

then the no. of coloum be x

total no of plants = no. of row × no. of coloum

2000 = x×x

2000 = x²

but 2000 is not a perfect sq. so we must add, subtract, multiply or divide it by a number but in quetion it is mention that he needa more plant so we add a no.

2000+25=x²

2025= x²

45= x²

hence farmer needs 25 more plants

.....666......
