Given :-

  • side of the square room = 12 m
  • rate of carpeting = Rs.5 per m²

To Find :-

  • Cost or carpeting the room ?

Solution :-

we know that,

  \boxed{\bold{area \: of \: square =  {side}^{2} }}

then,

 \bold{:  \implies  {12}^{2} } \\  \\  \bold{  : \implies 144 }

so, area of the room is 144 m²

then, cost of carpeting the room = 144 × 5 = Rs. 720

hence, cost of the carpeting the room is Rs. 720
