What examiners said

The majority of candidates knew that the bounds needed to be found before the calculation of the perimeter. This question involved lengths with a straightforward degree of accuracy of the nearest centimetre and, as a consequence, many candidates were confident with the values for the bounds that they needed to work with. This usually led to the correct answer, although some just added the length a...

Many candidates who realised that the first two zeros were not significant figures then drew a line between the 6 and the 2 in order to check the second significant figure. Unfortunately, quite a few added zeros after the correct answer which lost the mark. 0.05 was a common wrong answer as that was 2 decimal places.
