Make a plan for finding the area of the floor to be tiled. Include the geometric formulas you will use to find the area. Then find the area of the floor that will be tiled.

QUESTION 1

Cabinet

Not scaled to exact size.

Cabinet2 ft.

4 ft.

5 ft.

2 ft.

10 ft.

To find the area of the floor that will be tiled, you fi rst have to find the area of the cabinets. To find the area of the cabinets, you have to divide them into three separate shapes. There are two rectangles and one trapezoid. The area of the trapezoid is 9 ft. The area of the horizontal rectangle is 20 ft. The area of the vertical rectangle is 10 ft. Once you find the area of all three shapes, you add them together to find the total area of the cabinets. Then, you multiply the length and the width of the entire room to get 234 ft. Lastly, you subtract the area of the cabinets by the area of the whole room to find the area that needs to be tiled. The final answer is 195 ft.

QUESTION 1 (GEOMETRIC FORMULAS)

You estimate that it will take 4 minutes to install each square foot of tile. Find the number of hours it will take you to complete the job.

QUESTION 2

If installing a tile will take 4 minutes, then the whole project should take 13 hours. We figured this out by subtracting 234 minus 39 to get 195. Then multiply by 4 and you get 780. Then you divide it by 60 and you get 13 hours.

THE ANSWER QUESTION 2

Determine how much you will charge per hour for labor.

QUESTION 3

I plan to only charge $16.00 per hour for labor because it is right in between the highest and lowest costs.

COST FOR LABOR

What other costs do you need to consider? Write an expression to represent the cost of your expenses if the customer chooses a tile that costs t dollars per square foot.

QUESTION 4

The other expenses that we need to consider are the costs of the cement and labor. The expression to represent the cost of the expenses when the customer chooses a tile that costs t dollars per square foot is: t*195+($16.00*13.)

THE ANSWER TO QUESTION 4

How much will you charge if the owner of the kitchen shown above to install tile that costs $8.00 per square foot?

QUESTION 5

If the customer asks for tiles that cost $8.00 per square foot, to find the answer you have to have to take 195 ft. and you multiply it by 8 to get $1,560 You then add that to the cost of hourly labor, which is $208. Then add them together to get $1,768.
