What is the cost to steam clean a room w wide and l long if it costs 10 cents per square foot to clean it?
As area in a "room" is width times length, and, as it costs 10 cents per square foot to steam clean that room's floor, find the width and the length in feet, then multiply them together to find the area of the room in square feet, and then divide that area by 10 cents. You'll get the answer in cents. To find the answer in dollars, divide the area of the room by 0.1 dollars per square foot instead. Then you'll have your steam cleaning cost for the room in dollars. Area of the room = length x width (Insure that each is in feet. Convert if you have to.) Aroom = l x w Cost of cleaning = 10 cents per square foot, or $0.10 per square foot Cleaning cost = Aroom / 0.10 = Answer in $
