I believe B But I am not sure I hope this helps . =D
This is number 8. the second person got number 9
They would need to by 3 more tickets. 214 divided by 9 = 23 with the remainder of 3. So I divided 217 by 9 = 23. I added 3 to 214 which got a whole answer 23.
I hope I helped.
It’s going to be the area of the triangle on the side times the length, so 0.5 x 36 x 15 x 48 = 12960
