anonymous · Answer

Hmm, this is hard but I think it is B.

directrix · Answer

The lateral area will be the same formula as before:

LA = perimeter of triangular base times the height.

To that, add twice the area of one of the two triangular bases.

directrix · Answer

The perimeter of the base is  16 and the height is 10. That gives a lateral area of 160.

anonymous · Answer

That is confusing but um... 21? J.k. 54? I do not know!!! B.T.W I did not guess.

anonymous · Answer

wait I think that I am getting it!!!

directrix · Answer

Are you confused on the lateral area?  

Because that is all that I have done.

You may be working ahead of me.

haha. (;

directrix · Answer

The area of the triangular base is 1/2 times 6 times 4 which is 12.

anonymous · Answer

Ok...

directrix · Answer

160 for the lateral area added to 2*12 for the two bases gives 160 + 24
