Answer 3

@jim_thompson5910

Answer 4

same as last, show me while I add

Answer 5

390*9

Answer 6

perimeter?

Answer 7

=3,510

Answer 8

that is not quite the area

Answer 9

so notice that you have 390 cm<----you have to convert me to meters first

Answer 10

@jim_thompson5910

Answer 11

so, can you convert 390cm to meters please?

Answer 12

uh hello? @amberk123 , that was a bit rude and I am still here

Answer 13

okay i am trying

Answer 14

ok

Answer 15

the best way to approach this is to think about how many centimeters are in a meter

Answer 16

1 meter=100 centimeters

Answer 17

ok, so what could you multiply by that is just equal to one? Hint: you need to be able to cancel out the cm. \[\frac{390cm}{1}\times \frac{?}{?}\]

Answer 18

\[\frac{ 390 }{ 1 }x \frac{ 9 }{ 1 }\]

Answer 19

right

Answer 20

how did you get 9/1?

Answer 21

oh I see what you did, you need to change cm to meters first, ignore the 9m for now

Answer 22

okay

Answer 23

\[\frac{ 390 }{ 1}x \frac{ 100 }{ 1}\]

Answer 24

that is close, but you made cm^2/m with that multiplication

Answer 25

do i flip the 100 and 1

Answer 26

that is because \[\frac{ 390cm }{ 1}x \frac{ 100cm }{ 1m}=cm*cm/m\]

Answer 27

yes

Answer 28

39,000

Answer 29

i don't think so, give it another go

Answer 30

i times 390*100=39,000

Answer 31

perimeter of my D

Answer 32

how do you have times 100 if you flipped it?

Answer 33

\[\frac{ 390 }{ 1 }x\frac{ 1 }{ 100 }=\frac{ 390 }{ 100 }=3.9\]

Answer 34

there we go

Answer 35

so now you have: Find the perimeter

Answer 36

do u add 3.9 and 9

Answer 37

you do, but a rectangle has 4 sides, not just two

Answer 38

\[3.9+9+3.9+9=25.8\]

Answer 39

so the answer is A.25.8
