Question

transforme, as unidades de area em m²:

53 dm²=
127 dam²=
1,325 hm²=
0,18 km²=

Answer 1

53:4=13.25 m²
127:4=31.75m²
1,325:4=331.25m²
0,18:4=0,045m²

Answer 2

$53 \: {dm}^{2} = 53.0 \div 100 = 0.53 { m}^{2}$
$127 \: {dam}^{2} = 127 \times 100 = 12.700 { m}^{2}$
$1.325 \: {hm}^{2} = 1.325 = 132.5 \times 100 = 13.250 {m}^{2}$
$0.18 \: {km}^{2} = 0.18 = 018.0 \times 100 = 1.800 {m}^{2}$
