6th grade math

could someone solve the two and show work and maybe explain?

Hey!! 

So on number one, first you have to find out the area of the first triangle. That is B*H÷2. So that would be 3.4*3=10.2 Then 10.2÷2=5.1
That's the area of the first triangle. Now, 6 triangles can fit inside that hexagon. You would then do 5.1*6. That would be 30.6. 30.6 is your answer for the first problem.

You would do the same thing for the next problem. 12*12.5=150÷2=75 75*7=525
That would be your answer for number 2. 
Hope this helped! Make sure to check my calculations before turn in! 
Godspeed
