Question

100 square metres=___________ .

• A. $1$ square centimeters
• B. $1$ are
• C. $1$ hectare
• D. $10$ hectare

Answer 1

Answer: (B)

$1$ are

We know that:

$1cm=0.01m$ so $1c{m}^2=(0.01{)}^2{m}^2={10}^{-4}{m}^2$;

$1$ are $=100m^2$ and

$1$ hectare $={10}^4{m}^2$

So, $10$ hectare $={10}^5{m}^2$
