La figura mostrada se dividió en tres partes iguales para calcular su área.
levacccp [35]

Answer:

El área de un rectángulo de largo L y ancho A es: L*A.

El área de un triangulo de alto H y base B es: H*B/2.

Ahora veamos las tres figuras:

Rectángulo amarillo:

Largo = 40m

Ancho = 45m

Área = 40m*45m = 1800 m^2

Rectángulo blanco:

Largo = 40m

Ancho = 35m

Área = 40m*35m = 1400m^2

Triangulo azul:

Base = 35m

Alto = 50m

Área = 35m*50m/2 = 875m^2

Area total = 1800 m^2 + 1400m^2 + 875m^2 = 4075m^2
