Question

find the area of the triangle whose vertices are (2,3) (-1,0) (2,-4)

​

Answer 1

Answer:

the area will be 2, 6 3 e e

Answer 2

vertices are-

X1= 2. X2=-1. X3=2

Y1=3. Y2= 0 Y3=-4

Area Of Rectangle=

1/2[X1(Y2-Y3)+X2(Y3-Y1)+X3(Y1-Y2)]

=1/2[2(0+4)-1(-4-3)+2(3-0)]

=1/2[2×4-1×-7+2×3]

=1/2[8+7+6]

=1/2×21
