    yeah, its an area... because an area is two dimensional... do you know what that means?

    you would use the area for a triangle... which woud be base times height/2 so once you have the base height and hypotenuse, you can work it out right?

    ok, that should have worked, what did you do after you had the numbers in (how did you solve it)?

    by just following it through like nine squared is 81 and fifteen squared is 225

    then subtrected 81 from both sides to leave a by its self which was 174 the square root of tht is 13.1
