Answer 1

(18х9)+(8х11) = 162+88 = 250 м

Answer 2

Calculating the total amount of wallpaper purchased

According to the question, 18 rolls of wallpaper were purchased with 9 meters in each roll. So for the 18 rolls, the total length is:

18 rolls x 9 meters/roll = 162 meters

Additionally, 8 rolls were purchased with 11 meters in each roll. So for these 8 rolls, the total length is:

8 rolls x 11 meters/roll = 88 meters

To calculate the total length of all wallpaper purchased, we add the lengths of the two groups:

162 meters + 88 meters = 250 meters

Therefore, the total amount of wallpaper purchased was 250 meters.
