## Claire4christ 3 years ago I need help with a question i will download the question. Thanks

1. CliffSedge

Can ignore the height of the walls and just find the sq. ft. of the floor.

2. mustanggrandmomma

Determine the square footage of the room, then multiply that answer by the cost of the padding and the carpet, add the sums together to get your answer.

3. Claire4christ

10x12=120

4. CliffSedge

Multiply that by the sum of the costs-per-sq.ft. of the padding and carpet.

5. Claire4christ

3.88

6. Claire4christ

A bedroom is 10 ft. by 12. ft. with 8 ft. high walls. How much would it cost to put wallpaper in this room? Cost = \$

7. Claire4christ

@CliffSedge i dont get this one . i just did it but answer doesnt match.

8. CliffSedge

You need to find the surface area of the walls. Imagine what the room looks like and how big the walls are.

9. Claire4christ

8ft high

10. CliffSedge

Not just their height, their area.

11. Claire4christ

12. CliffSedge

Usually...

13. CliffSedge

I'm assuming we're not furnishing a Hobbit hole.

14. Claire4christ

15. CliffSedge

Yes, and you can assume 4 walls. You'll be overestimating because it's not taking into account doors or windows, but that's ok.

16. Claire4christ

:LxW

17. CliffSedge

You know how to do it. Work it all out and let me know what you get.

18. Claire4christ

8x8=64

19. CliffSedge

None of the walls are 8ft wide.

20. Claire4christ

you are right

21. Claire4christ

i know the are of a room so can find the W right

22. Claire4christ

120=8xw

23. Claire4christ

24. CliffSedge

Imagine knocking down all the walls until they laid flat with the floor. |dw:1349656277520:dw|

25. CliffSedge

The floor is 10 by 12, and two of the walls are 10 by 8, and the other two are 12 by 8.

26. CliffSedge

You can't divide the area of the floor by the height of the walls to find... well anything, they are not related like that.
