if the area of right triangle ABC is 4, and the hypotenuse $\overline{AB}$ is 12, then what is 2A?
Unless I am seriously misinterpreting the question, this question is nonsensical. A is a vertex of the triangle, so 2A makes no sense.
Yes, I am aware that in algebraic notation, 2A reprents A multiplied by 2, but I really do not understand what the question is asking currently. I must be missing something because you all are answering as if there is no comprehension gap. I must be missing something obvious. I am trying to be helpful, but I cannot until I understand the problem clearly.
What is A in this particular question? Is it a length of one of the legs of the triangle? Is it the measure of an angle? Is there a hidden diagram I am missing right now? I see a guest wrote 2A = 13 without any explanation whatsoever, so I know I am missing something. I am sorry for being an inconvenience.
