The absolute error is 2 feet and percent error is 18.18%
Step-by-step explanation:
Given,
Estimated length = 13 feet
Actual length = 11 feet
Absolute error = Estimated length - Actual length
Absolute error = 11 - 13 = -2 feet
Absolute error = 2 feet
Percent error = [tex]\frac{Absolute\ error}{Exact\ value}*100[/tex]
Percent error = [tex]\frac{2}{11}*100[/tex]
Percent error = [tex]\frac{200}{11}=18.18 \%[/tex]
The absolute error is 2 feet and percent error is 18.18%
