Answer 1

Answer:

VI521=39

39plants in 39 rows is the answers

Answer 2

Answer:

There are 39 rows.

Step-by-step explanation:

Gívєn -

Total trees = 1,521

Number of rows = Number of trees in a row

Tσ fínd -

The number of rows.

Sσlutíσn -

Let the number of rows as x

As Number of rows and Number of trees in a row are same ;

The Number of trees in a row will also be x

➡ Number of rows × Number of trees in a row = Total trees

➡ y × y = 1521

➡ y² = 1521

➡ y = $\sqrt{1521}$

➡ Prime Factorize 1521 =

$\begin{array}{r|l} 3 & 1521 \\\cline{1-2} 3 & 507 \\ \cline{1-2} 13 & 169 \\\cline{1-2} 13 & 13 \\\cline{1-2} & 1\end{array}$

1521 = 3 × 3 × 13 × 13 = $\sqrt{1521}$ = 3 × 13

➡ y = 3 × 13

➡ y = 39

Number of rows = 39

Number of trees in a row = 39

$\therefore$ There are 39 rows.
