Question

if A(x1 y1) b ( X2 y2 ) and c x3 y3) are the three vertices of the triangle ABC write the formula of area of the triangle ABC
​

Answer 1

• If the Vertices of Triangle ABC are A(x₁ , y₁) , B(x₂ , y₂) , C(x₃ , y₃)

Then The Area of Triangle ABC = 1/2 × [x₁(y₂- y₃) + x₂(y₃ - y₁ ) + x₃(y₁ - y₂)]
