Q.8  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.

Answers (1)

The total number of plants = No. of rows \times No. of plants in 1 row.

Since in this case  no.of rows = no. of plants in each row.

 Thus let us assume the number of rows to be x.

 Then the equation becomes   :        x^2 = 2025

Prime factorization of 2025 gives = 3 \times3\times3\times3\times5\times5

  So value of x is = 45.

Hence no. of rows = 45; and no. of plants in each row = 45.
