Question

What is the Area of triangle ABC, whose vertices are A(X,1Y1), B(x2,y2)and C(x3, y3)​

Answer 1

Step-by-step explanation:

Area of ∆ ABC will be 1/2 [ X1(y2-y3) + X2( y3-y1) + X3( y1-y2) ]

Answer 2

$\sf \red{A(x1,y1), \: B(x2,y2)}\: and \: \red{C(x3,y3)}\\ \\ \rm Area \: of Δ= \frac{1}{2} \left[ x1(y2−y3)+x2(y3−y1)+x3(y1−y2) \right] \\ \\ \frak{please \: mark \: my \: answer \: as \: brainliest..!!}$
