Question

15dm2 =…cm2. 1230cm2=… dm3…cm2. 5dm212cm2 =… cm2. 4300dm2=…m2…dm2

Answer 1

`15dm^2 = 15 xx 100 = 1500cm^2`

`1230cm^2 = 12dm^2 30cm^2`

`5dm^2`  `12cm^2 = 5 xx 100 + 12 = 512cm^2`

`4300dm^2 = 43m^2 0dm^2`

Answer 2

\(15dm^2=1500cm^2\) 

\(1230cm^2=12dm^230cm^2\) 

\(5dm^212cm^2=512cm^2\) 

\(4300dm^2=43m^2\)

Answer 3

15dm2=1500cm2
5dm2 12cm2= 512cm2
4300dm2=40m2 300dm2
