Higher November 2018 Unit 2 Q7
7. In this question, you will be assessed on the quality of your organisation, communication and accuracy in writing.
The perimeter of a square is 76·4 m.
Calculate the length of its diagonal.
You must show all your working. [4 + 2 OCW]
| Scheme | Marks | Comments |
|---|---|---|
| (Length of side = \(\dfrac{76{\cdot}4}{4}\) =) 19·1(m) | B1 | |
| (diagonal2 =) 19·12 + 19·12 | M1 | F.T. ‘their derived length of side’ (not 76·4) |
| diagonal2 = 729·6(2) or (diagonal =) √729·6(2) | A1 | Diagonal = 729·6(2) is A0 unless corrected in further work |
| (diagonal =) 27·0(..)(m) or 27(m) | A1 | F.T. 'their 729.6' provided M1 awarded and their answer is greater than 19·1. Award SC2 for a final answer of 108(·0…)(m) (from using 76·4(m) as side length) BUT In this case there is no credit given for sight of 19·1. |
