Best ResponseYou've already chosen the best response.0how did you arrive at (1/2)*9*9? How do you know the height of the triangle is 9?

Best ResponseYou've already chosen the best response.0the bottom part has a 9 and has a tick mark so all three sides are equal and 4 in the height

Best ResponseYou've already chosen the best response.0you have to calculate the height of the triangle and plug it in the formula 1/2 base*height. base is 9.

Best ResponseYou've already chosen the best response.0no, that is not right. http://math.about.com/od/formulas/ss/areaperimeter.htm In that picture, the area of the triangle is 1/2b*h. so, what do you know about an equilateral triangle that will make finding the height easier?

Best ResponseYou've already chosen the best response.0no, that is not the height of the triangle, it is the height of the prism. I am talking about the height of the triangle. The volume of the prism is the area of the triangle times the height of the prism, correct? so you know the height of the prism. Now you need to find the area of the triangle. So, in order to do that you need to find the height of the triangle, so that you can put it in the formula 1/2b*h.
