The answer is 231 because you need to multiply 7 by 6 first to get 42 and then multiply 42 by 11 to get 462. Lastly divide 462 divided by 2 to get 231 because the triangle is 1/2 the position and it's side lengths.
Therefore your answer is 231. I hope you do well on whatever test is coming up for you. (❁´◡`❁) (✿◡‿◡)
