25 The L-shape is made from rectangles.
Not drawn accurately
The area is 44 cm\(^2\)
Work out the perimeter. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| Alternative method 1 | ||
| \(4 \times 2\) or 8 | M1 | oe may be seen in an equation eg \(3 \times x + 4 \times 2 = 44\) |
| \(\dfrac{44 - 4 \times 2}{3}\) or \(\dfrac{36}{3}\) or 12 | M1dep | oe |
| 38 | A1 | |
| Alternative method 2 | ||
| \(7 \times 2\) or 14 | M1 | oe may be seen in an equation eg \(7 \times 2 + 3 \times y = 44\) |
| \(\dfrac{44 - 7 \times 2}{3}\) or \(\dfrac{30}{3}\) or 10 | M1dep | oe |
| 38 | A1 | |
Additional guidance
| Up to M2 may be awarded for correct work, with no or incorrect answer, even if this is seen amongst multiple attempts | |
| Working for up to M2 may be seen on the diagram | |
| Beware of 38 from incorrect working | |
| \(7 + 3 + 7 + 3 = 20\), \(7 + 2 + 7 + 2 = 18\), \(20 + 18 = 38\) | M0M0A0 |
