ABCD is a trapezoid with line BC perpendicular to line AB and line BC perpendicular to line CD. AB=13 BC=12 CD=8.A line segment is drawn from A to E, which is the midpoint of line CD. What is the area of triangle AED?
The trapezoid described is somewhat as the figure below:
The formula of the area of the triangle is
Since AF is perpendicular to the triangle's side DE, and AF=BC=12, we have:
