Debora [2.8K]

Answer:

16.8 metros cuadrados.

Step-by-step explanation:

Dado que 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, y que el área de un hexágono es igual al perímetro multiplicado por la apotema, y dicho resultado dividido por 2, para determinar cuál es el área que se va a pintar se debe realizar el siguiente calculo:

((6x3) x 2.8) / 2 = X

(12 x 2.8) / 2 = X

33.6 / 2 = X

16.8 = X

Así, el área que se va a pintar es de 16.8 m2.
