The area of a triangle can be calculated with the formula:

The base of the triangle is "b" and the height of the triangle is "h",
In the figure you can observe that the base and the height of the triangle are:

Knowing these values, you can substitute them into
.
Therefore, the area of the triangle is:


If the x is squared, the parabola is vertical (opens up or down). If the y is squared, it is horizontal (opens left or right). If a is positive, the parabola opens up or to the right. If it is negative, it opens down or to the left.
