Question

$1225$ plants are to be planted in a garden such a way that each row contains as many plants as the numbers of rows. Find the total number of rows.

• A. $25$
• B. $35$
• C. $50$
• D. $45$

Answer 1

The correct option is B $35$

Let no. of rows $=x$

Ans to ques,

No. of rows $\times$ no. of plants in each row =1225

$x\times x=1225$

$x^2=1225$

$x=\sqrt{1225}$

$x=\sqrt{7\times 7\times 5\times 5}$

$x=35$
