Answer :
Let the number of rows be x and x be the number of plants in each row.
∴we have total number of plants=\(x^2\) = \(\sqrt{2025}\)
\(\Rightarrow x=\sqrt{2401}\)
\(\qquad \begin{array}{c|lcr}
3 & 2025\\
\hline
3 & 675\\
\hline
3 & 225\\
\hline
3 & 75\\
\hline
5 & 25\\
\hline
5 & 5\\
\hline
& 1\\
\end{array}
\)
\(\Rightarrow \sqrt { 3\times 3\times 3\times 3\times 5\times 5 }\)
\(\Rightarrow \sqrt { { 3 }^{ 2 }\times { 3 }^{ 2 }\times { 5 }^{ 2 } }\)
\(\Rightarrow 3 \times 3 \times 5\)
\(\Rightarrow 45\)
Hence, the number of rows is 45 and the number of plants in each row is also 45
