Answer: 36

Step-by-step explanation:

The area of a triangle is (1/2)lw <- that just means that a triangle is half a square. Length * width is the original formula for solving the area of a square.

6 * 12 = 72; 72/2 = 36

36 because the triangle formula is half of base times height. Base times height would be 72 so half of that is 36
