Question

How can you find the area of a two-dimensional composite figure, or the surface area of a three-dimensional composite figure?

Answer 1

Step-by-step explanation:

a. the area of a two-dimensional composite figure

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

b. the surface area of a three-dimensional composite figure

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
