Answer:
2.5271%
Step-by-step explanation:
The percent error is defined as;
(error/actual value) * 100%
In this case the error will be;
27.7cm - 27.0cm = 0.7cm
The actual value is 27.7cm since it is the one specified by the manufacturer.
The percent error in the worker's measurement is thus;
(0.7cm/27.7cm) * 100 = 2.5271%
