Answer:
a) [tex]0.000324 km^2[/tex]
b) [tex]32400 dm^2[/tex]
c) [tex]3.24x10^6 cm^2[/tex]
Explanation:
To do the different conversions we need to know the follow:
[tex]1 km->1000 m so 1 km^2-> 1000^2 m^2= 1x10^6 m^2[/tex]
[tex]324 m^2*(1 km^2/1x10^6 m^2) = 0.000324 km^2[/tex]
[tex]1m-> 10 dm so 1m^2->10^2 dm^2=100 dm^2[/tex]
[tex]324 m^2*(100 dm^2/1 m^2)=32400 dm^2[/tex]
[tex]1m-> 100 cm so 1m^2->100^2 cm^2=10000 cm^2[/tex]
[tex]324 m^2*(10000 cm^2/1 m^2)=3.24x10^6 cm^2[/tex]
Answer :
(A) [tex]234m^2=2.34\times 10^8km^2[/tex]
(B) [tex]234m^2=2.34\times 10^4dm^2[/tex]
(C) [tex]234m^2=2.34\times 10^6cm^2[/tex]
Explanation :
The conversion used for area from [tex]m^2[/tex] to [tex]km^2[/tex] is:
[tex]1m^2=10^6km^2[/tex]
The conversion used for area from [tex]m^2[/tex] to [tex]dm^2[/tex] is:
[tex]1m^2=100dm^2[/tex]
The conversion used for area from [tex]m^2[/tex] to [tex]cm^2[/tex] is:
[tex]1m^2=10000cm^2[/tex]
Part (A):
As, [tex]1m^2=10^6km^2[/tex]
So, [tex]234m^2=\frac{234m^2}{1m^2}\times 10^6km^2=2.34\times 10^8km^2[/tex]
Part (B):
As, [tex]1m^2=100dm^2[/tex]
So, [tex]234m^2=\frac{234m^2}{1m^2}\times 100dm^2=2.34\times 10^4dm^2[/tex]
Part (C):
As, [tex]1m^2=10000cm^2[/tex]
So, [tex]234m^2=\frac{234m^2}{1m^2}\times 10000cm^2=2.34\times 10^6cm^2[/tex]
