Question

1 ${\text{m}}^2$ = ______ ${\text{cm}}^2$

Answer 1

1. Area is defined as, $\text{length×length}$
2. The SI unit of area is ${\text{m}}^2$.

1 metre = 100 centimetre,

On squaring both sides ,

${\left(1\mathrm{m}\right)}^2={\left(100\mathrm{cm}\right)}^2={10}^4{\mathrm{cm}}^2$

Hence, 1 m² = 100 cm².
