| Type | Parabola area calculations |
| Difficulty | Standard +0.8 This is a multi-step Further Maths question requiring knowledge of parabola properties (focus, directrix), coordinate geometry, and area calculations. Part (a) is straightforward recall, but part (b) requires setting up coordinates from the geometric constraints, finding intersection points, and computing the triangle area—more demanding than standard A-level but routine for FM students who know parabola theory. |

2. A parabola $P$ has cartesian equation $y ^ { 2 } = 28 x$. The point $S$ is the focus of the parabola $P$.
\begin{enumerate}[label=(\alph*)]
\item Write down the coordinates of the point $S$.
Points $A$ and $B$ lie on the parabola $P$. The line $A B$ is parallel to the directrix of $P$ and cuts the $x$-axis at the midpoint of $O S$, where $O$ is the origin.
\item Find the exact area of triangle $A B S$.\\
