The area of the triangle with vertices (1, minus 1), (minus 4, 6) and (minus 3, minus 5) is:
A18 square units
B28 square units
C12 square units
D24 square units
Answer & Solution
Correct answer: D. 24 square units
1. Apply the area formula to the three vertices.
2. The bracket works out to 48.
3. Half of that is 24 square units.
