Calculating Wallpaper Rolls Needed for Room

To calculate the number of wallpaper rolls needed to cover the room, we can follow these steps:

1. Calculate the Perimeter of the Room: - Perimeter = 2 * (length + width) - Perimeter = 2 * (4m + 7m) = 2 * 11m = 22m

2. Calculate the Total Area to Cover: - Total area = Perimeter * height - Total area = 22m * 2.75m = 60.5 square meters

3. Calculate the Area Covered by One Roll of Wallpaper: - Area covered by one roll = width of roll * length of roll - Area covered by one roll = 0.5m * 10m = 5 square meters

4. Determine the Number of Rolls Needed: - Number of rolls = Total area / Area covered by one roll - Number of rolls = 60.5 square meters / 5 square meters = 12.1 rolls

Conclusion

To cover the room with wallpaper, approximately 12 rolls of wallpaper will be needed. Keep in mind that it's always a good idea to purchase a little extra to account for any mistakes or miscalculations.
