Okay.

OpenStudy (anonymous):

Is it C? @DDCamp

OpenStudy (anonymous):

I think it's C.

OpenStudy (ddcamp):

How'd you get that?

OpenStudy (ddcamp):

It's close, but you may be forgetting that the area of a Triangle is \[A = \frac{1}{2} b h\]

OpenStudy (ddcamp):

if b=3 and h=2.6, each triangle has area: \[\frac{1}{2} (3) (2.6) = 3.9\]
