Answer 2

$\large\bf\underline{Given:-}$

• Number of plants = 1225
• plants are planted in such a way that each row contains as many as plants as the no of rows.

$\large\bf\underline {To \: find:-}$

• Number of rows and number of plants in each row.

$\huge\bf\underline{Solution:-}$

• Total plants = 1225

Let the number of rows be x

therefore ,

The number of plants in each row = x

▶️ Accourding to Question :--

Each row contains as many as plants as the number of rows.

Total number of plants = number of rows × number of plants in each row

↣1225 = x × x

↣1225 = x²

↣x = √1225

Finding square root of 1225

$\bf\large\begin{array}{r|l}5&1225\\\cline{2-2}5&245 \\ \cline{2 - 2}7&49 \\ \cline{2 - 2}7& 7 \\ \cline{2 - 2}&1\end{array}$

hence,

$\dashrightarrow \sf\: 1225 = \underbrace{5 \times 5} \times \underbrace{7 \times 7} \\ \dashrightarrow \sf\: 1225 = 5 \times 7 \\ \dashrightarrow \sf\:1225 = 35$

hence,

Square root of 1225 is 35

✝️So,

• Total number of rows = 35
• No. of plants in each row = 35
