It would help if you could specify what the area is in total, in order to find the perimeter with a variable.
Answer:
Perímetro = 8.925 metros
Step-by-step explanation:
La formula del perímetro de un rectángulo es:
perímetro = 2(ancho + largo)
en este caso:
p = 2(a+b)
a = 3b/4
b = 2.55m
a = ancho del rectángulo
b = largo del rectángulo
entonces:
sustituyendo el valor de la segunda ecuación
p = 2((3b/4)+b)
p = 2((3b/4)+(4b/4))
p = 2(7b/4)
p = 14b/4
p = 7b/2
p = 7*2.55/2
p = 8.925m
