Answer:
108
Step-by-step explanation:
Because the area formula is a*b and 12*9 is 180
So the answer is 180 which is A
I hope this helps :)
Answer:

c) x - 9
d) 12x
e) x²
f) x + 1
g) x - 20
h) 3x + 5
i) x - 3
Step-by-step explanation:
8 21/100

from the question, (-2,2) and (1,2) have the same y value so you can use that as your base and easily find the perpendicular height using the y axis since it's parallel to the x axis.
the third point, (0,-6), to the base is your height
use the sum of the positive of the y values to find your height (because height can't be negative): 6+2 = 8
area of a triangle = 1/2 bh = 1/2 x 3 x 8 = 12
Note: 1/2 bh only works because (-2,2) and (1,2) form a line parallel to the x axis
