if the scale is 1:20 then it meansd that each measurement would be 20 times bigger in real life than in the drawing

so - what are th edimansions of the real room in inches? (multiply th drawing by 20)

Answer 4

do you mean multiply 5 by 20 and 4 by 20

Answer 5

yes

Answer 6

so 100 and 80

Answer 7

well - you need to include the units

100 inches by 80 inches

so what is tharea of the room in square inches (multiply the lenght by the width)

Answer 8

8,000...?

Answer 9

square feet

Answer 10

Yes - but please include th eunits

8000 sq ins

but oyu need to convert to sq feet

how many sq ins in 1 sq ft?

Answer 11

144

Answer 12

i think, sorry i am really bad at this

Answer 13

OK good

so use that to convert 8000 sq ins to sq feet

(you need to divide....)

Answer 14

so divide 12 by 8000..right

Answer 15

no

area = 8000 sq ins
i sq ft = 144 sq ins

so how many sq ft are the same as 8000 sq ins

Answer 16

55?

Answer 17

why have you rounded it ?

Answer 18

o w8 its 144

Answer 19

not 55

Answer 20

No
8000/144 = 55.5555

You rounded to 55

but if you are choosing to round to nearest sq ft it is 56

or maybe choose 55.5 or 55.55

Answer 21

ok got it

Answer 22

thx for the help :)

Answer 23

the question doesn't tell you the accuracy required

but 55 is not good - because 56 is th e nearest whole number

or you could choose to put recurring decimal 55.555........
