C. 1/2(18 x 6)

Step-by-step explanation:

1/2 base x height is the equation used, so plug in the numbers and you get 1/2(18 x 6)

C

Step-by-step explanation:

We see that the shaded area of the rectangle is a right triangle. This is great for us.

The formula for finding the area of a triangle is (base*height)/2=area. Over here, the base is 18 and the height is 6, so we plug in those numbers and get (18*6)/2=108/2=54. I just went ahead and looked at all the answers knowing the answer but you can tell it isn't A or B because there is addition and you can tell it isn't A or C because it doesn't half it.

Please tell me if you have any questions.

you can't solve x because it is 2 linear equation and you only have one equation

to be honest i don't know but i need points so
