Question

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 1

Let the number of rows be x.
Therefore, the number of plants in each row is also x.
Total number of plants $=\left(x\times x\right)=x^2=1225$
$$\begin{gathered} x^2=1225=5\times 5\times 7\times 7 \\ x=\sqrt{1225}=5\times 7=35 \end{gathered}$$

Thus, the number of rows is 35 and the number of plants in each row is 35.
