Answer:
Percentage error in the student measurement = 2%
Step-by-step explanation:
Percentage error = (change in length) / actual length × 100
Approximate length =294 feet
Actual length = 300 feet
Percentage error = (change in length) / actual length × 100
= (300 feet - 294 feet) / 300 feet × 100
= 6/300 × 100
= 0.02 × 100
= 2%
Percentage error in the student measurement = 2%
