Final answer:
The total perimeter of the chicken coop with five equal sides of length 3√5 yards is 15√5 yards.
Step-by-step explanation:
The total perimeter of the chicken coop can be found by multiplying the length of one side by the number of sides. In this case, the length of one side is 3√5 yards and there are 5 sides.
Perimeter = Length of one side * Number of sides
Perimeter = 3√5 yards * 5
Perimeter = 15√5 yards
Therefore, the total perimeter of the chicken coop is 15√5 yards (option A).
