Carpet sells for $2 per square foot and will cost you $440 to recarpet your rectangular room. If your room is 20 feet long, how many feet wide is it?

Answer 1

That would be 4400 because 4.4 times 10^3

Answer 2

11

Explanation:

a square foot is the multiplication of length and width.

first, let's find the square feet(?)

$2-------1

$440----?

440/2=?/1

220=?

therefore, the room is 220 square foot

from the initial sentence

square foot= length × width

220= 20×w

w=11

therefore the room is 11 feet wide
