$a)$

$\circ 1m^2=100d{m}^2=10000c{m}^2=1000000m{m}^2$

GT: $1m^2=100d{m}^2$

$1d{m}^2=100c{m}^2$

$1c{m}^2=100m{m}^2$

$\circ 1ha=10000m^2$

$\circ 1k{m}^2=100ha=1000000m^2$

$b)$

$\circ 1m^2=0,01da{m}^2$

$\circ 1ha=0,01k{m}^2$

$\circ 1m^2=0,0001h{m}^2=0,0001ha$

GT: $h{m}^2=ha$

$\circ 4ha=0,04k{m}^2$

GT: $1ha=0,01k{m}^2$

$\circ 1m^2=0,000001k{m}^2$

a, 1m² = 100 dm² = 10000 cm² = 1000000 mmm²

   1ha = 10000 m² 

   1km² = 100 ha = 1000000m²
