Question

Carpet sells for $3 per square foot and will cost you $570 to recarpet your room. If your room is 19 feet long, how many feet wide is it?

Answer 1

First find your room's area: 570/3=190 square foot.
Area of rectangular= lenght*wide
190=19*x
x=10 is wide

Answer 2

first, divide your total (570) by 3 to make the problem simpler.

from there, you get 190... divide that (which is your area) by 19 ft, and you get 10.
the dimensions of the room are 19 feet by 10 ft
