    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,
    Hence, the area of the triangle is 24 square units.
    Therefore, the correct answer is option (1).
