Answer:
69.993
Step-by-step explanation:
Using the percentage error formula:
Percentage error = (true - measured value / true measurement ) * 100%
1% error in measurement
1% of 69.3
0.01 * 69.3 = 0.693
True measurement = error in measurement + measured value
True measurement = 0.693 + 69.3
Actual measurement = 69.993
Hence, actual measurement = 69.993.
