Calculating Wallpaper Needed for Room

To calculate the amount of wallpaper needed to cover the walls of a room, we can use the following formula:

Total wallpaper needed = (Perimeter of the room - area of windows and doors) / size of each wallpaper roll

Let's calculate the total wallpaper needed step by step.

1. Calculate the Perimeter of the Room: - Given: Length of the room = 6m, Width of the room = 5m - Perimeter = 2 * (Length + Width)

The perimeter of the room is: ``` Perimeter = 2 * (6m + 5m) = 2 * 11m = 22m ```

2. Calculate the Area of Windows and Doors: - Given: Window size = 1.5m - Area of the window = Height * Width - Since the height is not provided, we'll assume a standard height of 2m for the window.

The area of the window is: ``` Area of window = 2m * 1.5m = 3m² ```

3. Calculate the Total Wallpaper Needed: - Given: Size of each wallpaper roll = 0.5m

Now, we can calculate the total wallpaper needed using the formula: ``` Total wallpaper needed = (Perimeter of the room - area of windows and doors) / size of each wallpaper roll Total wallpaper needed = (22m - 3m) / 0.5m Total wallpaper needed = 19m / 0.5m Total wallpaper needed = 38 rolls ```

So, to cover the walls of the room, excluding the windows and doors, 38 rolls of wallpaper will be needed.
