     \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

    \rule{200}3
