Answer 2

$\huge \red{ answer}$

$\large \purple{ \underline{given} - \: length \: of \: room = 6m \: } \\ \large \purple{breath \: of \: room = 4m} \\ \large \purple{side \: of \: square \: carpet = 3m}$

$\bf \green{aera \: of \: room = \boxed{length \times breath} \: \: \: (coz \: outer \: room \: is \: rectangle) } \\ \bf \green{aera \: of \: room \: = 4 \times 6} \\ \bf \green{aera \: of \: room = 12m {}^{2} \: } \\ \\ \bf \blue{aera \: of \: carpet = \boxed{side {}^{2}} \: \: \: (coz \: carpet \: is \: square) } \\ \bf \blue{ aera \: of \: carpet = 3 {}^{2} } \\ \bf \blue{aera \: of \: carpet = 9m {}^{2} } \ \\ \ \\ \bf \pink{aera \: of \: floore \: not \: carpeted \: = \boxed { aera \: of \: room \: - \: aera \: of \: carpet}} \\ \bf \pink{aera \: of \: floore \: not \: carpeted = 12 - 9} \\ \bf \pink{aera \: of \: floore \: not \: carpeted \: = 3m {}^{2} }$
