Answer:
El área total a pintar será:
Step-by-step explanation:
Sabiendo el apotema y la longitu de los lados, podemos encontrar el área de un triangulo. Recordemos que, si trazamos rectas del centro del hexágono a los vértices, se formaran 6 triángulos equiláteros.
El área de un triángulo es:
b es la longitud de la base (b=3 m)
a es la apotema, osea la altura del triangulo (a = 2.8)
Ahora, solo debemos mutiplicar ese valor por 6 para determianr el área total de la pared.

Answer:
The answer is 10x - 10y - 9

Answer:
$25.20
Step-by-step explanation:
