The formula for the area of a triangle is 1/2 times the base times the height (A = ½ bh). Option B, ah, simply multiplies the base and height together, while option C, (b + h) / 2, adds the base and height before dividing by 2 which will not result in the correct answer. Option D, b(h + 1), incorrectly adds 1 to the height instead of multiplying it by 1/2. This is why option A, ½ bh, is the correct choice for finding the area of a triangle.
