Daniel tiene un terreno agrícola de 12 ha. Se sabe que el 20% del terreno está sembrado de árboles frutales, y el 25%, de hortalizas. ¿Cuántos metros cuadrados ha destinado Daniel para estas plantaciones?

árboles frutales ... 24 000 m²

hortalizas ... 30 000 m²

Total... 54 000m²

Step-by-step explanation:

Convertimos las 12 ha en metros

cuadrados

1 ha = 10 000 m²

12 ha = 120 000 m²

Árboles frutales

Calculamos el 20 % de 120 000 m²

(0.20 ) (120 000) = 24 000 m²

hortalizas

Calculamos el 25% de 120 000 m²

(0.25) (120 000) = 30 000 m²

Si queremos saber el total del terreno sembrado, sumamos

24 000 m² + 30 000 m² = 54 000 m²
