$\:\:$

• Number of trees in each row is equal to number of rows in a garden

$\:\:$

• Total number of trees in the garden is 7921

$\:\:$

$\large{\red{\underline \bold{\tt{To \: Find :-}}}}$

$\:\:$

• Number of rows of trees

$\:\:$

$\large{\orange{\underline{\tt{Solution :-}}}}$

$\:\:$

• Let the number of rows be "x"

$\:\:$

$\purple{\underline \bold{According \: to \: the \ question :}}$

$\:\:$

Number of trees in each row = Number of rows

$\:\:$

Thus ,

$\:\:$

➠ Number of trees in each row = x

$\:\:$

$\underline{\bold{\texttt{Total number of trees :}}}$

$\:\:$

Number of trees in each row × Number of rows

$\:\:$

➜ x × x

$\:\:$

Given that there are 7921 number of trees

$\:\:$

So,

$\:\:$

➜ x × x = 7921

$\:\:$

➜ x² = 7921

$\:\:$

➜ $\sf x = \sqrt { 7921 }$

$\:\:$

➨ x = 89

$\:\:$

• Hence there were 89 rows of trees in the garden
