By converting the $$5.6\ m^2$$ into the $$cm^2$$, the answer will be
Correct option is C. $$56000\ cm^2$$
As we know that,
$$1\ m = 100\ cm$$
So,
$$1\ m\times 1\ m=100\ cm\times 100\ cm$$
$$\Rightarrow 1\ m^2 = 10000\ cm^2$$
By using the above conversion,
$$5.6\ m^2 = 5.6\times 10000\ cm^2$$
$$=56000\ cm^2$$
Hence, option $$C$$ is correct.
