Answer: The answers could be 162 mm^2, 189 mm^2, or 84 mm^2
Explanation:
(Since the base and height aren't listed, the answers might be wrong.)
A (of a triangle) = 1/2 * b * h
If b = 27 and h = 12, we first divide 12 by 2. 27 * 6 = 162 mm^2
If b = 27 and h = 14, we first divide 14 by 2. 27 * 7 = 189 mm^2
If b = 12 and h = 14, we first divide 14 by 2. 12 * 7 = 84 mm^2
