Answer 1

13*90=1170
11*80=880
1170+880=2050
2050-1440=610

Answer 2

Calculation of Remaining Fabric

To calculate the amount of fabric remaining after using 1440 meters, we need to subtract the amount used from the total amount of fabric available.

In the sewing workshop, there were 13 rolls of fabric, each containing 90 meters, and 11 rolls of fabric, each containing 80 meters.

The total amount of fabric available can be calculated as follows:

13 rolls of fabric * 90 meters per roll = 1170 meters

11 rolls of fabric * 80 meters per roll = 880 meters

Therefore, the total amount of fabric available is 1170 meters + 880 meters = 2050 meters.

To find the amount of fabric remaining after using 1440 meters, we subtract 1440 meters from the total amount of fabric available:

2050 meters - 1440 meters = 610 meters.

Therefore, there are 610 meters of fabric remaining after using 1440 meters.
