A notebook of length 15 cm was measured to be 16.8 cm, calculate, correct to two d.p, the percentage error in the measurement.
-
12.00%
- 11.71%
- 10.71%
- 11.21%
The correct answer is: A
Explanation
Error = 16.8 - 15 = 1.8cm
% error = \(\frac{error}{ Actual value}\times 100%\)
= \(\frac{1.8}{ 15}\times100%\)
= \(0.12\times100%\)
= 12.00%
