Not drawn accurately
The area of the wall is 39.2 m\(^2\)
Work out the length of the wall. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(\dfrac{1}{2} \times (2.8 + 2.1)\ (\times h)\) or \(2.45(h)\) | M1 | oe eg \(2.1(h) + 0.5(h) \times 0.7\) any letter may be implied |
| \(\dfrac{1}{2} \times (2.8 + 2.1) \times h = 39.2\) or \((2.8 + 2.1) \times h = 39.2 \times 2\) or \(39.2 \div 2.45\) or \(78.4 \div 4.9\) | M1dep | oe equation or calculation |
| 16 | A1 | SC1 8 |
Additional guidance
Different letter used eg \(2.1h + 0.5x \times 0.7\) is M0 unless recovered
