Carpet sells for $3 per square foot and it will cost you $648 to re- carpet your room. If your room is 18 feet long, how many feet wide is it?

Question

Carpet sells= $3 Per square foot

re-carpet= $648

room long= 18 feet

wide= ??

Answer 1

Total area to be re-carpeted is:

 

 648 / 3 = 219 square feet

 

 Room Length * Room Wide = 216 square feet

 We know Room Length = 18 feet

 So, the Room Width = 216 / 18 = 12 feet

Answer 2

Silvana,

 

Cost of carpeting the room is $648

 

Carpet sells for $3 per sq foot, so Area of the room = 648/3 = 216 sq ft

 

Room is 18 feet long

 

Area= 18*width = 216

 

Width = 216/18 = 12 ft
