Step-by-step explanation:
The given points are A(-2,3) , B(3,-5). , C(2,-1)
To find the area using these three points one must form those three exactly the triangle
The area of triangle = 1/2 [ x1(y2-y3)+x2(y3-y1)+x3(y1-y2)]
= 1/2[(-2)(-5-(-1))+3(-1-3)+2(3-(-5))]
= 1/2[-2(-5+1)+3(-4)+2(3+5)]
=1/2 [-2(-4)-12+2(8)]
=1/2 [8-12+16]
= 1/2[24-12]
= 1/2[12]
=6
therefore the area of triangle equal to 6
