Calculating the Amount of Tape Needed for Carpet

To calculate the amount of tape needed for the carpet, we can use the formula:

Area = Length × Width

Given: - Length of the carpet = 27 m - Width of the carpet = 17 dm

First, we need to convert the width from decimeters to meters: 1 decimeter (dm) = 0.1 meters

So, the width of the carpet in meters = 17 dm × 0.1 m/dm = 1.7 m

Now, we can calculate the area of the carpet: Area = 27 m × 1.7 m = 45.9 square meters

Conclusion

To cover the entire carpet, you would need approximately 45.9 square meters of tape.
