Calculation of Average Daily Painted Area by Painters

To calculate the average daily painted area by the painters, we need to add up the total area painted each day and divide it by the number of days worked.

According to the information provided, the painters painted 100 meters of wall on the first day, 50 meters on the second day, 49 meters on the third day, and the remaining 91 meters on the last day.

To find the average daily painted area, we sum up the total area painted and divide it by the number of days worked.

Total area painted = 100 meters + 50 meters + 49 meters + 91 meters = 290 meters

Number of days worked = 4 days

Average daily painted area = Total area painted / Number of days worked

Average daily painted area = 290 meters / 4 days = 72.5 meters

Therefore, the painters painted an average of 72.5 square meters per day.
