5 ABCDE is a pentagon.
Work out the area of the pentagon. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(\dfrac{1}{2} \times (14 + 20) \times 11\) or 187 | M1 | oe any correct method to find the area of the trapezium |
| \(\dfrac{1}{2} \times 10 \times 7\) or 35 | M1 | oe eg \(\dfrac{1}{2} \times 10 \times 7 \times \sin 90\) |
| 222 | 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 | |
| Ignore Pythagoras’ theorem, trigonometry or perimeter calculations | |
| \(14 \times 11 + \dfrac{1}{2} \times 6 \times 11\) | M1 |
| Missing brackets must be recovered eg1 \(\dfrac{1}{2} \times 20 + 14 \times 11\) and 187 eg2 \(\dfrac{1}{2} \times 20 + 14 \times 11\) | M1 M0 |
| \(20 \times 11 = 220\) | M0M0A0 |
