please answer for area <3 thank you! (:

Answer:
9x+36
Step-by-step explanation:
With the given equation Area=1/2(Base*Height), all you need to do here is plug in base and height. The height here can be either side, since you're finding the area of a right triangle, but let's use 18 as the height. If 18 is the height, then x+4 is the length.
Plugging these into the equation gives us:
Area=1/2(18(x+4)
Area=9(x+4)
Area=9x+36
Step-by-step explanation:
1/2 x( 18 x X+4)
That simplified would be like 9 x ((x/2)+2)
Or I'm just over thinking and it's the 1st thing I said ""-w-
