Plss help me, I have to find area

C: 191.

Step-by-step explanation:

The total area of this is a little less than 15 x (3+4+10) = 15 x 17 = 255.

So then we subtract that by 36, which is the rectangle that is missing from the shape. So 255-36 = 219.

So now we have to guess. The triangle seems a little small, so it has to be the largest option, which is C: 191.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
