What is the area of a triangle that has a height of 8 feet and a base length of 5 feet?

I wanna say 40ft, but you can correct me if I'm wrong.

The answer is 20. What you gotta do is multiply 8 by 5 to get 40, then divide it by 2 because it is half of a rectangle/parallelogram, so 40 divided by 2 is 20. Hope this helps, and the brainliest answer would be appreciated. :D
