can you show me step by step?

Answer 5

follow the outline
what is the area of the room?

Answer 6

487 x 427?

Answer 7

yes and the unit for the area cm x cm = cm^2

Answer 8

so, 207949 cm ^2?

Answer 9

now how would you convert from cm^2 to m^2?

Answer 10

all i know is ''1 square meter = 100 x 100 square centimeters''

Answer 11

lets apply that.
100 x 100 cm^2 = 1m^2 and you have 207949 cm^2 so you need to divide

Answer 12

divide by 1000?

Answer 13

10000 yes

Answer 14

207.949

Answer 15

m^2

Answer 16

Answer 19

now round it to the nearest whole squaremeter

Answer 20

20.7949

Answer 21

what is the closest whole number?

Answer 22

its either 20 or 21?

Answer 23

note that if you did the conversion first then found the area you would get the same result

Answer 24

20.7 is closer to 20 or 21?
remember if more than 1/2 0.5 then add
answer would be 21 m^2
