Answer:
341 centimeters
Explanation:
The question is wanting to know how much wallpaper (in centimeters) was removed. Since your wanting your answer in centimeters make sure that all your measurements are in centimeters first. We see that one piece is measured in meters, so to covert it from meters to centimeters we multiply by 100 because they're are 100 centimeters in a meter.
1.5×100= 150 centimeter
Now we can add all the lengths together
110+150+81= 341 centimeters
Hope this helped!
