Bahasa Melayu
Sebuah kilang kecil menghasilkan $x$ balang jem Jenis A dan $y$ balang jem Jenis B dalam tempoh seminggu. Keadaan penghasilan itu dimodelkan oleh
$0.3x + 0.1y \ge 9$, $0.1x + 0.2y \ge 8$, $0.05x + 0.05y \le 3.5$,
bersama $x \ge 0$ dan $y \ge 0$.
Rantau $R$ yang memenuhi kelima-lima ketaksamaan itu ialah sebuah segi tiga. Cari luas, dalam unit persegi, bagi rantau $R$.
$0.3x + 0.1y \ge 9$, $0.1x + 0.2y \ge 8$, $0.05x + 0.05y \le 3.5$,
bersama $x \ge 0$ dan $y \ge 0$.

English
A small factory produces $x$ jars of Type A jam and $y$ jars of Type B jam in one week. The production conditions are modelled by
$0.3x + 0.1y \ge 9$, $0.1x + 0.2y \ge 8$, $0.05x + 0.05y \le 3.5$,
together with $x \ge 0$ and $y \ge 0$.
The region $R$ that satisfies all five inequalities is a triangle. Find the area, in square units, of the region $R$.
