You can use it to find the area of a right triangle because a right triangle is basically a rectangle cut in half diagonally. However, this formula does not apply to all triangles because those that are not right triangles don't have a base or height, they're not really a rectangle. Because the formula for a rectangle's area is bxh, a right triangle is half of that. I hope this made sense and was helpful. :)
