Find the area (in square units) of a triangle whose vertices are (1, -1), (-4, 6) and (-3, -5).
Answer & explanation
Correct answer: option 2
Given that the coordinates of the triangle are (1, -1), (-4, 6), (-3, -5).
Let (x1, y1) = (1, -1)
(x2 , y2) = (-4, 6)
(x3 , y3) = (-3, -5)
The formula to calculate area is given by,
