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
