$5416643811828\mathrm{.}93zqy7$

Given the corner points of a triangle $(x_1,y_1),(x_2,y_2),(x_3,y_3)$ compute the ai

Hint: The area of the triangle with corner points $(0,0),(x_1,y_1),$ and $(x_2,y_2)$ is

$\frac{|x_1*y_2-x_2*y_1|}{2}$

@param $y2$ the $y-$coordinate of the second corner

@param $x3$ the $x-$coordinate of the third corner

Qparam $y3$ the $y-$coordinate of the third corner

@return the area of the triangle
