3. How much space do I want? How much space do I need?
Why type of apartment would you like when you first move out on your own?
How can apartments that have the same square footage look completely different?

4. Example 1
Jerry is using the floor plans for his new home to help him purchase base molding for the place where the walls meet the floor. The plans are drawn using a scale of ¼ inch represents 1 foot. He measures the walls on the floor plan with a ruler and finds that they total 23½ inches. If molding costs $2.10 per foot, how much will Jerry spend on molding?

5. CHECK YOUR UNDERSTANDING
a) On a floor plan, a rectangular room is 4 inches by 6 inches. What is the actual perimeter of the room in feet if the scale used is ½ inch = 1 foot?
b) The length of a room is 17 feet. When using ½ inch = 1 foot scale, what is the length of the room on a floor plan?

6. Example 2
Gabriela plans to carpet her living room, except for the quarter-circle shown in the corner. That area will be a wood floor where she will put her piano. The radius of the quarter circle is 8 feet. If carpeting costs $9.55 per square foot, what is the cost of the carpeting she will use in her living room?

7. CHECK YOUR UNDERSTANDING
Express the area of the shaded region in the room shown algebraically.

8. EXAMPLE 3
Delgado’s Landscape Design is building a large gazebo for a backyard. It is in the shape of a regular octagon as shown in the diagram. Each side of the gazebo is 10 feet. They need to purchase wood for the floor. It costs $14 per square foot for a special type of wood. Find the cost of the gazebo’s floor.

9. CHECK YOUR UNDERSTANDING
A regular pentagon (5 sides) has a side length of 6 feet and the apothem of the pentagon is 8 feet. What is the area of the pentagon?

10. EXAMPLE 4
Don sculpts out a region for a flower garden, as shown. He takes a digital picture of the garden. The irregular region would fit inside a rectangle that is 15 yards by 20 yards. He superimposes a 15 by 20 grid over the photo on his computer. The area of the garden impacts the cost of mulch, plants, fertilizer, and so on. To find its area, 1,000 random points are generated, and 631 of them land inside the irregular region. What is the area of the garden?

11. EXAMPLE 5
The living room in Julie’s apartment is 14 feet by 16 feet with an 8-foot ceiling. What is the volume of the room?

12. CHECK YOUR UNDERSTANDING
In example #5, if Julie wanted to paint the room, how many square feet would she have to cover?
