anonymous · Answer

drop a perpendicular line down from -b,c or b,c to the x axis and then use Pythagorean theorem to find the diagonal length.  By dropping a perpendicular line down, you get the base and the height.

thats what i have to do, or thats my answer?

anonymous · Answer

that is the process for finding the answer.  try it and post your answer.  I can check it.

anonymous · Answer

but there are no numbers, how do i find this?
i am so confused

anonymous · Answer

ok, your height is c.  That is the distance from (-b,c) to the x axis.  your base is the distance from (-b,c) to (a,0).  (b+a).
