To find the percentage error, we will use the formula:
Percentage error = (Measured value - Actual value) / Actual value * 100%
Measured value = 1.80 cm
Actual value = 1.75 cm
Percentage error = (1.80 - 1.75) / 1.75 * 100%
Percentage error = (0.05 / 1.75) * 100%
Percentage error = 0.0285714 * 100%
Percentage error ≈ 2.857%
Since none of the given answer choices match with the calculated percentage error, there is no correct option.
