Problem Analysis

To solve this problem, we need to calculate the total length of wallpaper purchased for the apartment renovation. We are given that the length of a roll of white wallpaper is 16 meters, and the length of a roll of brown wallpaper is 4 meters less than the white wallpaper roll. Additionally, we know that 5 rolls of white wallpaper and 4 rolls of brown wallpaper were purchased.

Calculation

Let's calculate the total length of wallpaper purchased for the apartment renovation.

The length of a roll of white wallpaper is 16 meters. The length of a roll of brown wallpaper is 4 meters less than the white wallpaper roll.

Therefore, the length of a roll of brown wallpaper is 16 - 4 = 12 meters.

The number of rolls of white wallpaper purchased is 5. The number of rolls of brown wallpaper purchased is 4.

To calculate the total length of wallpaper purchased, we multiply the length of each roll by the number of rolls and add them together.

Total length of white wallpaper = 16 meters/roll * 5 rolls = 80 meters. Total length of brown wallpaper = 12 meters/roll * 4 rolls = 48 meters.

Therefore, the total length of wallpaper purchased for the apartment renovation is 80 meters + 48 meters = 128 meters.

Answer

For the apartment renovation, a total of 128 meters of wallpaper were purchased.
