Question

a gardener has 1400 plants he wants to plant these in such a way that the number of rows and number of columns remains same find the minimum number of plants needs for this

pls answer it because day after tomorrow is my exam

Answer 1

Find the square root of the number...
=square root of 1400 is 37 point something..am not sure, jus tried to answer

Answer 2

let the number of rows =x
number of rows × number of columns= total number of plants
x×x=1400
x(square)=1400
${37 }^{2} < 1400 < {38}^{2}$

1369<1400<1444
1444-1400=44
therefore we need 44 more plants to make 1400 as a perfect square
therefore answer is 44 plants
