Hey there, Ashytyn!
Area of a triangle, any triangle, is defined as base times height divided by two.
Why?
Think about if this right triangle was a rectangle. You'd multiply the four times the two for the area, right? Now we first have to realize that this triangle is half of a rectangle, and <em>that's why</em> we divide by two.
Therefore, we have:
A =
A = 2(4)/2
A = 8/2
A = 4 units squared.
Hope this helps!
