Question 9 Squares and Square Roots Exercise 3D

1225 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:

Given: the number of plants to be planted = 1225

Let the number of rows be ‘x’

Therefore, the number of plants in each row are also ‘x’

Total number of plants = (x × x) = x2=1225

Shifting the square, we get

√1225 = 5 × 7 = 35

Therefore, the number of rows id 35, and the number of plants in each row is also 35
