The perimeter of fenced off portion is 60 yards.
Step-by-step explanation:
Given,
Area of fenced off portion= A² = 225 square yards
Taking square root on both sides;
[tex]\sqrt{A^2}=\sqrt{225}\\A=15\ yards[/tex]
Therefore, one side of fenced off portion is 15 yards.
As the fenced off portion is in square form, therefore,
Perimeter = 4*side of square
[tex]P=4*15\\P=60\ yards[/tex]
The perimeter of fenced off portion is 60 yards.
