Answer:
The Answer is 6.
Step-by-step explanation:
Area of triangle = 1/2 [ x_{1} (y_{2} -y_{3} ) + x_{2} (y_{3} - y_{1})+x_{3}(y_{1}-y_{2})
As given the vertices at (−2, 1) , (2, 1) , and (3, 4)
put in the equation above
we result with
= 1/2 [-2(1-4)+ 2 (4-1) + 3 ( 1-1) ]
solving
= 1/2 [6 + 6]
therefore
= 1/2 [12]
=6
area of the triangle is 6 units².
