Mathematics

Step-by-step explanation:

<u>a. the area of a two-dimensional composite figure</u>

In this situation, we need to draw any necessary segments to view the figure as basic shapes, then:

  • Step 1: add basic shape areas belonging to the composite shape
  • Step 2: subtract basic shape areas NOT belonging to the composite shape

<u>b. the surface area of a three-dimensional composite figure</u>

As we know (3D) composite objects are made of two or more objects put together. To find the surface area of a 3D composite object, we need:

  • Step 1:  find the outside surface area of each object
  • Step 2: add the surface areas together

Hope it will find you well
