Problem Analysis

To solve this problem, we need to find the total number of meters of wallpaper purchased. We are given that 16 rolls of wallpaper were bought for the walls, with each roll containing 12 meters, and 4 rolls were bought for the ceiling, also with each roll containing 12 meters.

Calculation

To find the total number of meters of wallpaper purchased, we can calculate the sum of the meters of wallpaper for the walls and the meters of wallpaper for the ceiling.

The number of meters of wallpaper for the walls is calculated by multiplying the number of rolls for the walls (16) by the number of meters per roll (12): Meters of wallpaper for the walls = 16 rolls * 12 meters/roll = 192 meters.

The number of meters of wallpaper for the ceiling is calculated by multiplying the number of rolls for the ceiling (4) by the number of meters per roll (12): Meters of wallpaper for the ceiling = 4 rolls * 12 meters/roll = 48 meters.

To find the total number of meters of wallpaper purchased, we add the meters of wallpaper for the walls and the meters of wallpaper for the ceiling: Total meters of wallpaper purchased = Meters of wallpaper for the walls + Meters of wallpaper for the ceiling = 192 meters + 48 meters = 240 meters.

Answer

Therefore, a total of 240 meters of wallpaper were purchased.
