3. Area Application #1 Painting Chris hung too many posters! When the posters were pealed off the wall, a lot of paint came off too. Chris wants to repaint that wall.

4. Area Application #1 Painting Paint costs $23.00 per gallon and covers 250 - 400 ft 2. How much will it cost to repaint the wall? How many gallons are needed?

5. Area Application #1 Painting Step 1: We need to find the area of the wall. Which formula must we use? Rectangle A = lw Rhombus A = ½d 1 d 2 13 feet 8 feet 6 feet 3 feet

6. Area Application #1 Painting Rectangle A = lw Great job! Continue!

7. Area Application #1 Painting Rhombus A = ½d 1 d 2 Sorry! Go back and try again!

8. Area Application #1 Painting Step 2: Using A = lw, calculate the area of the wall without the door. A = (13)(8) – (3)(6) = 86ft 2 A = (13)(8) + (3)(6) = 122ft 2 13 feet 8 feet 6 feet 3 feet

9. Area Application #1 Painting A = (13)(8) – (3)(6) = 86ft 2 Great job! Continue!

10. Area Application #1 Painting A = (13)(8) + (3)(6) = 122ft 2 Sorry! Go back and try again!

11. Area Application #1 Painting Step 3: The wall is 86ft 2 and Chris wants 2 coats of paint. How many gallons are needed and what is the cost? *Paint is $23.00 per gallon and covers 250 – 400 ft 2. 1 can - $23.00 2 cans - $46.00

12. Area Application #1 Painting 1 can - $23.00 Great job! Continue!

13. Area Application #1 Painting 2 cans - $46.00 Sorry! Go back and try again!

14. Area Now we can paint! Continue! Application #1 Painting

15. Area Application #2 Carpeting Amy wants to re-carpet the nursery. 9 feet 8 feet 10 feet 15 feet

16. Area Application #2 Carpeting Step 1: Determine the nursery’s shape. 9 feet 8 feet 10 feet 15 feet Parallelogram Trapezoid

17. Area Application #2 Carpeting Parallelogram Sorry! Go back and try again!

18. Area Application #2 Carpeting Trapezoid Great job! Continue!

19. Area Application #2 Carpeting Step 2: Using the trapezoid area formula, A = ½h(b 1 +b 2 ), determine the floor’s area. 9 feet 8 feet 10 feet 15 feet A = ½(10)(9+15) = 120ft 2 A = ½(8)(9+15) = 96ft 2

20. Area Application #2 Carpeting A = ½(10)(9+15) = 120ft 2 Sorry! Go back and try again!

21. Area Application #2 Carpeting A = ½(8)(9+15) = 96ft 2 Great job! Continue!

22. Area Application #2 Carpeting Step 3: Carpeting costs $2.07 / ft 2. How much will it cost to carpet the nursery since it’s 96ft 2 ? $2.07 (96) = $198.72 96 ÷ $2.07 = $46.38

23. Area Application #2 Carpeting $2.07 (96) = $198.72 Great job! Continue!

24. Area Application #2 Carpeting 96 ÷ $2.07 = $46.38 Sorry! Go back and try again!

25. Area Application #2 Carpeting Now we can carpet! Nice job!
