The area of a triangle is calculated using the formula: Area = 0.5 * base * height
In this case, the base of the scale drawing is 8 inches and the height is 2 inches.
Area = 0.5 * 8 * 2
Area = 0.5 * 16
Area = 8 square inches
Therefore, the area of Crystal's scale drawing is 8 square inches.
So the closest answer choice is 6.4 square inches.
