se quiere pintar una pared en forma de hexágono regular y se sabe que cada lado mide 3m y que su apotema es de 2,8m cual es el a

qwelly [4]

Answer:

El área total a pintar será:

$A_{tot}=25.2\: m^{2}$

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:

$A_{t1}=\frac{b*a}{2}$

b es la longitud de la base (b=3 m)

a es la apotema, osea la altura del triangulo (a = 2.8)

$A_{t1}=\frac{2.8*3}{2}$

$A_{t1}=4.2\: m^{2}$

Ahora, solo debemos mutiplicar ese valor por 6 para determianr el área total de la pared.

$A_{tot}=25.2\: m^{2}$
