Answer:
Percent error is approx. 22%
Step-by-step explanation:
So to do this you need to know the formula for percent error, which is
percent error = l measured - theoretical / theoretical l * 100%
With this just plug in 18 (real) and 14 (measured).
percent error = l 14 - 18 / 18 l * 100%
percent error = l -4 / 18 l *100%
percent error = l -2/9 l *100%
You then do absolute value because the percent error must be positive not negative! So -2/9 becomes 2/9. You then divide 2/9 to get approx. 0.22... and you muliply by 100% to get 22%.
