How can you decompose the composite figure to determine its area? as two semicircles and a rectangle as two circles and a rectangle as a circle and a square as two semicircles and a trapezoid picture is attached

as two semicircles and a rectangle

Step-by-step explanation:

If you extend the radii shown, each becomes an end of the rectangle, and also a boundary for a semicircle. The result is two semicircles and a rectangle.

Of course, two semicircles make a circle, so you could also decompose this to a circle and a rectangle.
