The y intercepts are -1 and 4 respectively so the base of the triangle is {{{B=4(-1)=5}}}
The height of the triangle is {{{2}}}.
You can also find this using the intersection point of the two lines by setting them equal to each other,
{{{2x-1=-(x/2)+4}}}
{{{4x-2=-x+8}}}
{{{5x=10}}}
{{{x=2}}}
So,
{{{A=(1/2)BH=(1/2)(5)(2)=5}}}
