Add the lengths of the two bases together, and then multiply by the height. Finally, divide by 2 to get the area of the trapezoid.

Multiply the lengths of the two diagonals together, and then divide by 2. This will give you the area of the kite.

In this example, we can determine the area of two triangles, a rectangle, and a trapezoid, and then add up the areas of the four shapes to get the total area.
