Percentage of Error in Measurement:
To find the percentage of error in the measurement, we need to calculate the difference between the actual length and the measured length, and then express that difference as a percentage of the actual length.
Given Information:
Measured length = 97 metres
Actual length = 100 metres
Calculation:
Step 1: Calculate the difference between the actual length and the measured length.
Difference = Actual length - Measured length
Difference = 100 - 97 = 3 metres
Step 2: Express the difference as a percentage of the actual length.
Percentage of Error = (Difference / Actual length) * 100
Percentage of Error = (3 / 100) * 100
Percentage of Error = 3%
Explanation:
The percentage of error in the measurement is 3%. This means that the measurement is 3% less than the actual length.
In this case, the girl measured 97 metres instead of the actual length of 100 metres. The difference between the measured length and the actual length is 3 metres. To express this difference as a percentage, we divide the difference by the actual length and multiply by 100.
The correct option is A) 3.0, which represents the percentage of error in the measurement.
To find the percentage of error in the measurement, we need to calculate the difference between the actual length and the measured length, and then express that difference as a percentage of the actual length.
Given Information:
Measured length = 97 metres
Actual length = 100 metres
Calculation:
Step 1: Calculate the difference between the actual length and the measured length.
Difference = Actual length - Measured length
Difference = 100 - 97 = 3 metres
Step 2: Express the difference as a percentage of the actual length.
Percentage of Error = (Difference / Actual length) * 100
Percentage of Error = (3 / 100) * 100
Percentage of Error = 3%
Explanation:
The percentage of error in the measurement is 3%. This means that the measurement is 3% less than the actual length.
In this case, the girl measured 97 metres instead of the actual length of 100 metres. The difference between the measured length and the actual length is 3 metres. To express this difference as a percentage, we divide the difference by the actual length and multiply by 100.
