If a triangle has a base of 4 inches and a height of 3 inches, what is the area?

To determine the area of a triangle, the formula used is:

Area = (1/2) × base × height

In this scenario, the base of the triangle is 4 inches, and the height is 3 inches. Plugging these values into the area formula gives:

Area = (1/2) × 4 inches × 3 inches

Area = (1/2) × 12 square inches

Area = 6 square inches

This calculation clearly shows that the area of the triangle is 6 square inches. Using this formula will yield the correct area for any triangle as long as the measurements of the base and height are known. Thus, the correct answer is indeed 6 square inches, corresponding to the second choice.
