Step-by-step explanation:

Number of rows-x

Number of chairs in each row-3x

Total chairs= x*3x

Answer 2

✪GIVEN:-

• No. of rows of chairs = x
• No. of chairs each row contains = 3x

✪FIND:-

• what is the total no. of chairs = ?

✪SOLUTION:-

$\rm ✥ no. \: of \: chairs \: in \: each \: rows = 3x$

$\rm ✥and \: no. \: of \:rows = x$

✴Then,

$\rm ✻total \: no. \: of \: chairs = no. \: of \: rows \times no. \: of \: chairs \: in \: each \: row$

$\rm➤x \times 3x$

$\rm➤3 {x}^{2}$

$\rm ➧ Thus, \: there \: are \boxed{ \rm 3 {x}^{2} }chairs.$
