B. 6.4 square inches
To find the area of the scale drawing, first find the scale factor by dividing the height of the actual triangle by the height of the scale drawing:
5 in / 2 in = 2.5
Next, square the scale factor to find the area scale factor:
2.5^2 = 6.25
Finally, multiply the area of the actual triangle by the area scale factor:
5 in * 8 in * 0.5 * 0.5 = 6.4 square inches
