Find the area of one of the outer triangles and multiply that by the number of outer triangles.
OpenStudy (anonymous):
You do then find the area of the figure inside and add it to the area of the triangles.
OpenStudy (anonymous):
the triangles would be 3*4*6=72 ... right?
OpenStudy (anonymous):
\[\frac{1}{2}*h*b=\triangle\]

oops right
OpenStudy (anonymous):
h=3
b=4
OpenStudy (anonymous):
so 36
OpenStudy (anonymous):

OpenStudy (anonymous):
yes

I don't know how to solve the inside shape. Anyone care to help out?
OpenStudy (amistre64):
apothem is height of triangles that make up the inner shape
OpenStudy (amistre64):
6(apothem*base/2)
OpenStudy (anonymous):
which is 3.46 (apothem)
OpenStudy (amistre64):
stick with 2sqrt(3) since thats what the answers use as well

so would the would the formula to find the inside figure be.. 6(2√3*4/2)
OpenStudy (amistre64):
yes
OpenStudy (anonymous):
okay then once I find that i times that number and 36 (from the outside triangle) to get the answer?
OpenStudy (amistre64):
you need to add, not times
OpenStudy (amistre64):
but yes
