cual es el área de este pentágono?
Ayuda pliss
Respuestas a la pregunta
Formula del Área pentágono
A= (perimetro* Apotema)/2
Datos:
P=35 cm
Ahora calculamos el apotema
Ap= L/(2 tan (θ))
donde
L= longitud del lado
como calcular θ
θ=360°/2*n
donde
n= numero de lados en este caso
n= 5 ya que es un pentágono
Entonces:
θ=360°/2*5
θ=36°
ahora si calculemos el apotema
Ap= 7/(2 tan (36°))
Ap= 4.81cm
calculando el área
A= (perimetro* Apotema)/2
A=(35*4.81)/2
A=84.175cm^2
Espero haberte ayudado
