Responda:
0,004816 m²
Explicação passo a passo:
Dado que :
Dimensão da tela retangular do celular = 5,6 cm por 8,6 cm
A área de um retângulo = comprimento * largura
Área da tela do celular = 5,6 cm * 8,6 cm = 48,16 cm²
A área em m²:
1m² = 10000cm²
Conseqüentemente,
(48,16 / 10.000) m²
= 0,004816 m²
