AA = 1.0 * b * h
BA = 2.0 * b * h
CA = 0.5 * b * h
DA = 0.5 * b + h
Answer & Solution
Correct answer: C. A = 0.5 * b * h
1. Area measures the space enclosed by the triangle, not its boundary length.
2. The formula uses two measurements: the base, b, and the height, h.
3. Multiplying the base by the height and taking one-half of that product gives the area.
