h- 1437,16 cm²


Essas são as questões que estão emboladas porque eu escrevi rápido !!,

se não entender fale por favor !!

Me ajuda ai por favor !!

Answer 1

km² = quilômetro quadrado                                                                                                                   hm² = hectômetro quadrado                                                                                   dam² = decâmetro quadrado                                                                                                                      m² = metro quadrado                                                                                                 dm² = decimetro quadrado                                                                                              cm² = centímetro quadrado                                                                                                                         mm² = milímetro quadradodo                                                                                                                                                                                                                                                                                                                                                                                        MAIOR para o menor (multiplica)==================>                                 km²      |    hm²    | dam²     |   m²     |   dm²     |    cm²      | mm²     <==================do menor para o MAIOR(divide)(atenção)

849,16 cm² = 849,16 : (100x100) =                                                                                                                            849,16 cm² = 849,16 : 10.000 = 0,084916 m²


f) 87,50 dm²
87,50 dm² = 87,50 : (100) =
87,50 dm² = 87,50 : 100=0,875 m²

h) 1437,16 cm²
1437,16 cm² = 1437,16 : (100x100) =
1437,16 cm² = 1437,16 : 10.000 = 0,143716m²
