| Topic | Sine and Cosine Rules |
| Type | Triangle area calculation |
| Difficulty | Easy -1.8 This is a straightforward application of the standard formula for triangle area (½ab sin C) with all values directly given. It requires only substitution into a memorized formula with no problem-solving, making it significantly easier than average and typical of a warm-up question worth only 2 marks. |
| Spec | 1.05c Area of triangle: using 1/2 ab sin(C) |
Triangle $ABC$ has $AB = 8.5$ cm, $BC = 6.2$ cm and angle $B = 35°$.
Calculate the area of the triangle. [2]
