To find the area of the scale drawing, we need to use the scale factor to find the new base length of the triangle in the drawing.
Scale factor = height of scale drawing / actual height
Scale factor = 2 / 5 = 0.4
New base length = actual base length * scale factor
New base length = 8 * 0.4 = 3.2 inches
Now we can find the area of the scale drawing:
Area = (1/2) * base * height
Area = (1/2) * 3.2 * 2
Area = 3.2 square inches
Therefore, the area of Crystal's scale drawing is 3.2 square inches.
