Question

1. Find the area of the triangle whose vertices are
(2,3), (-1.0, 2-4)​

Answer 1

Answer:

A(2,3) B(-1,0) C(2,-4)

X1=2         X2=-1        X3=2

Y1=3          Y2=0        Y3= -4

1/2  {x1(y2-y3) + x2(y3-y1) + x3(y1-y2)}

1/2 {2(0-(-4)) + (-1) (-4-3) + 2(3-0)}

1/2 {8-(-7)+6}

1/2 {8+7+6}

1/2 * 21

21/2
