Answer
The area of a SAS triangle is equal to the product of two sides and the sine of their included angle.
Work Step by Step
We know that the area $K$ of a triangle can be computed using the formula
$K=\frac{ab\cdot \sin{(C)}}{2}$, where $C$ is the included angle of $a$ and $b$.
Hence, the area of a SAS triangle is the product of two sides and the sine of their included angle.
