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

Rock musician Donny West is paid 15% on his CD sales and tour video sales. Last year, he sold one million CDs and 550,000 videos

olganol [36]

He had $5,000,000 in CD sales; $3,300,000 in video sales; and he earned $1,245,000 in royalties.

1,000,000 CDs * $5 each = $5,000,000
550,000 videos * $6 each = $3,300,000

Total sales = 5,000,000+3,300,000 = 8,300,000
15% royalties = 0.15(8,300,000) = 1,245,000
