Use the image to answer the question.
An illustration shows a triangle with a base of 20 inches and a perpendicular height of 6 inches. The height is a dashed line from the top vertex to the base, splitting the triangle in half, thus forming two triangles. A right angle symbol is shown where the dashed line meets the base, on the right side.
What is the area of the triangle shown?
