Unit Conversion
What is 5131 feet^2 into kilometers^2

Answer 1

\[\frac{ 5131ft^2 }{ 1 }\times \frac{ ?km}{ 1ft }\times \frac{ ?km }{ 1ft }\]
1ft=?km
You can search online to get the ?(how much km is 1ft) and put it in the conversion.
I put ft x ft in the denominator because it would cancel with the ft^2 out.
I put km x km on top because you want km^2
Denominator=numerator in a conversion problem except for the first one.
