Answer:
A. 64 square units
Explanation:
The area of a triangle is denoted by: A = (1/2) * bh, where b is the base and h is the perpendicular height to the base.
Here, we can say that side AB is the base with length 10, while the perpendicular segment extending from C to AB with length 12.8 is the height. Then, plug these in:
A = (1/2) * bh
A = (1/2) * 10 * 12.8 = 5 * 12.8 = 64
The answer is thus 64 square units, or A.
