$43,24 \ \text{m}^{2} = 43,24( 100^2 \ \text{cm}^{2}) = 43,24 (100^{-3} \ \text{km}^{2}) = 43,24(100^{-2} \ \text{hm}^{2})$
$53,21 \ \text{cm}^{2} = 53,21 (100^{7} \ \text{nm}^{2}) = 53,21(100^{4} \ \mu \text{m}^{2}) = 52,21(100^{-2} \ \text{m}^{2})$
$172,4 \ \text{m}^{2} = 172,4( 100^{6} \ \text{mm}^{2}) =172,4(100^{-9} \ \text{Tm}^{2}) = 172,4(100^{9} \ \mu \text{m}^{2})$
$233,5 \ \text{Gm}^{2} =233,5 (100^{9} \ \text{m}^{2}) = 233,5(100^{-3} \ \text{Tm}^{2}) =233,5(100^{21} \ \text{pm}^{2})$
