Question

how to find area of triangle​

Answer 1

Answer:

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

Answer 2

Step-by-step explanation:

FORMULAS FOR FINDING AREA OF TRIANGLE:

1. AREA OF ∆ = 1/2 B× H

2. AREA OF ∆ (EQUILATERAL) = √3/2 (a)^2

3. AREA OF ∆ = 1/2(X1(Y2-Y3) + X2(Y3-Y1) +X3(Y1-Y2)
