Carpet sells for $2 per square feet and will cost you $312 to re-carpet your room. If your room is 13 feet long. How many feet wide is it?
Answer provided by our tutors
let
w = the width of the room
l = 13 ft the length of the room
A = w*l the area of the room in ft^2
the price is $2 for 1 ft^2
If the area of the room is A ft^2 then the total cost will be $(2*A).
We know that the total cost is $312 thus we can write
2*A = 312
2*w*l = 312
2*w*13 = 312
w = 312 / 26
w = 12 ft
The room is 12 ft wide.
