Question 3663: What is the cost in dollars to steam clean a room W yards wide and L yards long if the steam cleaners charge 10 cents per square foot? Answer by Zenock(15) (Show Source):
You can put this solution on YOUR website! This is simular to the one I answered earlier...
There are 3 feet in a yard.
The width of the room in feet is: 3*W
The length of the room in feet is: 3*L
The area of the room in square feet is: (3*W)(3*L)=9WL
The cost is $.10 * 9WL = $.90WL
This makes sense because it equates to 90 cents a square yard and there are 9 square feet in a square yard.
