Question

*2025 plants are to be planted in a garden in such a way that each row contains as
many plants as the number of rows. Find the number of rows and the number of
plants in each row.​

Answer 1

Answer:

X=no.of plants=no.of rows

So,

X^2=2025

X=√2025

X=45

Hence no. Of rows=no.of plants=45

Answer 2

Answer:

Given:-

Total no. of plants=2025

Number of plants in each row=Number of rows.

To find:-

Number of rows and the number of plants in each row.

Write the expression for total number of plants:-

Total no. of plants=(Number of rows)×(Number of plants in each row)

Also, No. of rows=No. of plants in each row(Given)

Let the number of rows=No. of plants in each row as x.

Therefore,

Above equation becomes,

Total number of plants=(x)×(x)=(x)²

$\small \sf{x = \sqrt{(total \: number \: of \: plants)} }$

Factorise the number of plants:-

The total number of plants is 2025.

2025=(5×5)×(3×3)×(3×3)

No, unpaid number therefore it is a perfect square.

Find the square number of the number:-

2025=(5×5)×(3×3)×(3×3)

Therefore,

x=√2025=5×3×3=45.

“x” which is the value of no. of rows/no.of plants in each row.

Therefore,the number of rows and the number of plants in each row is 45.
