One hectare is equal to 10,000 sq. $ \mathrm{m} $. How much will this be in sq. $ \mathrm{cm} $ ? Express your answer in scientific notation.

Given:

One hectare is equal to 10,000 sq. \( \mathrm{m} \).

To do:

We have to find its value in sq. \( \mathrm{cm} \) and express it in scientific notation.

Solution:

We know that,

$1\ m=1\ cm$

Therefore,

$10000\ m^2=10000\ (100\ cm)^2$

$=10000\times(100)^2\ cm^2$

$=10000\times10000\ cm^2$

$=100000000\ cm^2$

$=10^8\ cm^2$

Hence, one hectare is equal to $10^8\ cm^2$ in scientific notation.
