Solution:
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,
Therefore, the correct answer is option (1).
Find the area of the triangle whose vertices are (1, -1), (-4, 6), (-3, -5).
