@welshfella

5. welshfella

well as the scale is 1:20 you multiply the width and the length by 20

6. welshfella

then multiply these to give you the area of the actual bathroom in sq ins

7. welshfella

to convert to sq ft you divide this area by 144

8. welshfella

sorry gotta go right now

9. anonymous

like Welsh said... multiply the width and length by 20

14. anonymous

so i do $3.5\times20$ and $2\times20$

15. Vocaloid

yes

16. anonymous

i got 70 and 40

17. Vocaloid

right, now find the area

18. anonymous

how?

19. Vocaloid

area = (width)*length

20. anonymous

whats the area?

21. Vocaloid

you just calculated the width and length area = width*length

22. anonymous

i got 70 x 40= 2800

23. Vocaloid

right, now divide by 144

24. anonymous

19 with a remainder of 64

25. Vocaloid

right, now round to the nearest whole number

26. anonymous

20

27. Vocaloid

other way 19.4444 rounded to the nearest whole number is...?

28. anonymous

oh 19.5

29. Vocaloid

whole number, not decimals

30. anonymous

19

31. Vocaloid

right

32. anonymous

so 19 is the answer for sure? do you know how to check the answer to make sure its right?

33. Vocaloid

yes, 19 is the answer to check your answer, you just need to make sure you multiplied everything right, which you did

34. Michele_Laino

hint: the real measures are: 3.5*20=...inches 2*20=...inches

35. anonymous

70 and 40

36. Michele_Laino

ok! now 70 inches correspond to 70/12=... feet and 40 inches correspond to 40/12=... feet

37. anonymous

i got 5 with a remainder of 10 and 3 with a remainder of 4

38. Michele_Laino

better is: 70/12 = 5.84 40/12=3.34

39. Michele_Laino

so the requested area is: 5.84*3.34=...feet^2

40. anonymous

19.5056

41. Michele_Laino

yes! now we have to round off to the nearest whole number, so what do you get?

42. anonymous

19

43. Michele_Laino

that's right!

44. anonymous

thanks

45. Michele_Laino

thanks! we have to thank to @Vocaloid for her good answer
