Answer with explanation:

Number of choices in Length for a dress = 3

Number of choices in Color for a dress= 5

Number of choices in Style for a dress= 2

To select a length out of 3 length ,which can be done in
$_(1)^(3)\textrm{C}$

To Select a color, among 5 different colors , can be done in
$_(1)^(5)\textrm{C}$ .

To Select a Style, among 2 different styles , can be done in
$_(1)^(2)\textrm{C}$ .

Total Number of ways

$=_(1)^(5)\textrm{C}*_(1)^(3)\textrm{C}*_(1)^(2)\textrm{C}\\\\= 5 * 3 * 2\\\\=30$
