Question

Sameer plant $7225$ plants. So that there are as many rows as there are trees in a row. How many trees are in a row?

Answer 1

We have to find the square root of the total number of trees by Prime factorization of $7225$

$$\begin{gathered} 7225=5\times 5\times 17\times 17; \\ \sqrt{7225}=\sqrt{(5\times 5\times 17\times 17)} \\ \sqrt{7225}=85 \end{gathered}$$

Therefore, the square root of $7225$ is $85$

Hence, $85$ plants are there in the row.
