Again, the right angle is not indicated in the image, nor do you state that the image is to scale. As a result, the answer technically could be either 6 root 3 or 1.5 root 3 depending on whether angle C or A is the right angle. If you don't specify which is the right angle or that the image is to scale, it's possible that it's out of scale to see if you're paying attention and trick you if you're not.
