Part A
Your bedroom has a rectangular shape and you want to measure its size. You use a tape that is precise to 0.001 m m and find that the shortest wall in the room is 3.547 m m long. The tape, however, is too short to measure the length of the second wall, so you use a second tape, which is longer but only precise to 0.01 m m. You measure the second wall to be 4.79 m m long. Which of the following numbers is the most precise estimate that you can obtain from your measurements for the area of your bedroom?
A) 17.0m^2
B) 16.990m^2
C) 16.99m^2
D)16.9m^2
E)16.8m^2
