So: Absolute Error = 7.25 m2 Relative Error = 7.25 m2 = 0.151... 48 m2 Percentage Error = 15.1% (Which is not very accurate, is it?) Volume And volume Measuring instruments are not exact! If a number of different people carry out the same measuring procedure and the values are close the procedure is reproducible. Shall i just make it up?
