You are purchasing carpet for a rectangular room in your house, but first you need to calculate the exact area of the room.  You measure the length of one wall with a measuring tape that reads to the nearest quarter inch and find that the wall is 180.25 inches.  Your roommate measures the wall with her measuring tape, which reads to the nearest tenth of an inch, and finds the wall is 179.6 inches.  Blueprints of your house reveal that the true length of the wall is 180.0 inches. Which measurement is more precise? Justify your answer clearly using quantitative evidence.           Which measurement is more accurate? Justify your answer clearly using quantitative evidence.           The true width of the room is 18 ft. What is the area of the floor in square feet?         Home Depot will charge $11/ft2 for the carpet you want, and Lowe’s will charge $80/yd2 for the same carpet. Which store offers the better bargain?
