There is no value of b in the diagram?

anonymous · Answer

but I think they are solving for the area, right?

mackenzie2013 · Answer

You have to find B you take 1/2(B)(h)

anonymous · Answer

Oh yeah the area of the base that's what I thought they were asking.
here the height is the distance of the dotted line which is 3.5 and the base b=the side length which is 4

mackenzie2013 · Answer

So 3.5 times 4? Then divided by 2?

anonymous · Answer

Yes, and that is the value of B. What do you get when you do that?

mackenzie2013 · Answer

Then you take 7 and times it by the height?

mackenzie2013 · Answer

Yeah, none of this makes sense to me..
