The answer would be 18 because the formula for the area of a triangle is 1/2times base times height. So first you cut half of the base or the height then you times the base and height together.
ie base= 6 height=6
1.) cut half of either so you get 3
2.) then times them both 3 times 6 is 18
32 is the answer
Your answer is 16√3 units2
