Units are required in this question for full marks to be awarded.
4600 cm2 (A1)(ft) (C1)
Notes: Units are required unless already penalized in part (a). Follow through from their part (a).
\(0.5(x + 92) \times 75 = 4600\) (M1)(A1)(ft)
OR
\(0.5 \times 150 \times (92 - x) = 4600\) (M1)(A1)(ft)
Note: Award (M1) for substitution into area formula, (A1)(ft) for their correct substitution.
