A=1/2 BH
the area of a triangle is half of the basexheight.
If the base of a triangle is 10, and the height is 4, you would take half of either 10 or 4 (doesn't matter), and then times them together and you have the area.
EX: A=1/2 10x4
(Take half of ten)
A=5x4
A=20
NEVER take half of both numbers. Only 1!
