Sagot :

Answer:

F. 1080

Step-by-step explanation:

Just like any shape, we get to do base x height! If you haven't located the base yet it's the right triangles. So first we have to find the area of the triangle and then multiply by the height (20). Lets find the area of the triangle first. To get the area you do (length x width)/2. 9*12/2=54. Now 54*20=1080
