Final answer:
The area of the scaled copy of the right triangle with a scale factor of 2 is 72 square units.
Step-by-step explanation:
To find the area of the scaled copy of the right triangle, we need to square the scale factor and multiply it by the area of the original triangle. Since the scale factor is 2, the area of the scaled copy will be 2^2 * 36 = 4 * 36 = 144 square units. So, the correct answer is d) 72 square units.
