Answer:
5.34%.
Step-by-step explanation:
Given that,
Measured length of a line = 13.8 inches
Actual length of the line = 13.1 inches
We need to find the percent error of the measurement. We can find it as follows :
[tex]\%=\dfrac{|measured-actual|}{actual}\times 100\\\\\%=\dfrac{13.8-13.1}{13.1}\times 100\\\\\%=5.34\%[/tex]
So, the required percentage is equal to 5.34%.
