Question

A gardener has 1300 saplings. He wants to plant these in such a way that the number
of columns and the number of rows remain same. Find the least number of more saplings
he needs for this.
Pls

Answer 1

Answer:

69

Step-by-step explanation:

let no. of rows be r and columns be c

r = c

no. of saplings = r×c

= r²

if there r = 37 = c

then no. of saplings = 37² = 1369

no. of saplings Gardener has = 1300

no. of saplings needed= 1369-1300

= 69

Answer 2

let the number of rows be x

and number of columns be y

sapling= x*y

we find the square root of 1300 = 36.0556------

so in this case number of rows and the number of columns not remain same

so we come to next perfect suare  that 1369  square root of 37

so he need the plants to maintain the number of rows and columns = 1369-1300 = 69

hope tis will help you
