Intermediate November 2024 Unit 2 Q2
2. In this question, you will be assessed on the quality of your organisation, communication and accuracy in writing.
Owen says,
“If the longer side of a rectangle is doubled and the shorter side is halved, then the perimeter of the rectangle will stay the same.”
Is Owen correct?
Show clearly, using an example, how you decided. [4 + 2 OCW]
| Scheme | Marks | Comments |
|---|---|---|
| One example of a pair of relevant rectangles or squares considered with the longer side correctly doubled and the shorter side correctly halved. | S1 | Sketch shown or lengths clearly stated. |
| Correct method of finding the perimeter of either rectangle/square. | M1 | FT one of ‘their rectangles/squares’ if lengths/width explicitly stated or shown on diagram. If only one rectangle or square is considered, award S0M1 if the correct perimeter or method of finding the perimeter is shown. |
| Correct perimeters found for both rectangles/squares AND statement that Owen is incorrect (or a statement that the perimeters aren’t the same). | A2 | Award A1 for one of the following:
If area is used instead of perimeter: S1 can be awarded for one example of a pair of relevant rectangles or squares considered and an additional SC1 could be awarded for their two (clearly identified) correct areas AND statement that Owen is correct. |
| Organisation and Communication. | OC1 | For OC1, candidates will be expected to:

| Accuracy of writing. | W1 | For W1, candidates will be expected to:
