The problem statement is about the estimation of error in computation, here we will be presented with two values, the actual and the estimated value.
The present error in Irene’s measurement is 11.1%
Given data
Actual value = 40 inch
Estimate value = 45 inch
The formula for calculating the percent error is given as
Percent error = (Actual - Estimated/Estimated) *100
Percent error = (40 - 45/45) *100
Percent error = (-5/45) *100
Percent error = (-0.111) *100
Percent error = 11.1 %
Hence the percent error is 11.1%
