How can you decompose the composite figure to determine its area?
a) as a circle, three rectangles, and a triangle
b) as a circle, a trapezoid, and four triangles
c) as a semicircle, three rectangles, and a square
d) as a semicircle, a trapezoid, and two rectangles

D) As a semicircle, a trapezoid, and two rectangles.

Step-by-step explanation:

In order to find the area of the composite figure provided, it is necessary to descompose it.

Observe the image attached.

You can observe that it can descomposed as:

1- A semicircle, whose area can be calculated with this formula:

Where r is the radius.

2- A trapezoid,  whose area can be calculated with this formula:

Where h is the height, B is the larger base and b is the minor base.

3- Rectangle.

4- Rectangle.

The formula for calculate the area of a rectangle is:

Where l is the lenght and w is the width.
