Calculation of Total Wallpaper Length

To calculate the total length of wallpaper purchased, we need to add up the lengths of the silk wallpapers and the paper wallpapers.

Given: - 6 rolls of silk wallpaper, each with a length of 12 meters. - 4 rolls of paper wallpaper, each with a length of 16 meters.

To find the total length of wallpaper, we can multiply the number of rolls by the length of each roll and then add the results together.

Calculation for silk wallpaper: - Number of rolls: 6 - Length of each roll: 12 meters - Total length of silk wallpaper: 6 * 12 = 72 meters.

Calculation for paper wallpaper: - Number of rolls: 4 - Length of each roll: 16 meters - Total length of paper wallpaper: 4 * 16 = 64 meters.

To find the total length of wallpaper, we add the lengths of the silk and paper wallpapers: - Total length of wallpaper = Total length of silk wallpaper + Total length of paper wallpaper - Total length of wallpaper = 72 meters + 64 meters = 136 meters.

Therefore, a total of 136 meters of wallpaper were purchased for the two rooms.
