In any trapezoid, the area is given by
where B and b are the two bases, and h is the height. You're given all these elements already, so you only need to plug the values in:
X-int: (6,0) & (4,0)
Y-int: (0,-12)
Vertex: (5, 1/2)
AOS: x=5
Max/Min Value: (5, 1/2)

It needs permutations of the order does matter, like 3 people ordering from a coffee shop to see who goes first.
Combinations are when the order doesn't matter, like if you had 3 numbers behind your back and you had to guess the 3 not in order
It needs neither when you don't need to find the amount of choices you have (or something similar) for something
