Calculating the Amount of Tape Needed for Carpet Laying

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

Tape Length = (2 * Length of the Carpet + 2 * Width of the Carpet)

Given: - Length of the carpet = 2 m - Width of the carpet = 15 dm

Calculation

Using the given values, we can calculate the tape length needed for the carpet laying:

Tape Length = (2 * 2 m + 2 * 15 dm)

Tape Length = (4 m + 30 dm)

To add the measurements, we need to convert 30 dm to meters: 1 dm = 0.1 m

Tape Length = (4 m + 3 m)

Tape Length = 7 m

Therefore, the tape length needed for the carpet laying is 7 meters.
