You are correct that each side is 9 feet.
But that wasn't the question. How much fence do you need to fence all 4 sides of 9' each?
A) 18 ft, B) 41 ft C) 36 ft D) 9Ft
I came up with D 9 foot but apparently I didn't work it correctly. Could someone explain how to work this.
Thank you

Since the garden is in the shape of a square, all sides will have equal length. Let's call the length of each side "x".
To find the perimeter, we add up all the sides of the square. In a square, all sides are equal, so the perimeter formula is:
Perimeter = x + x + x + x = 4x
We know the area of the square garden is 81 square feet. The formula for finding the area of a square is:
Area = side length * side length
81 = x * x
To find the value of x, we can take the square root of both sides of the equation:
√81 = √(x * x)
9 = x
Now that we know the side length of the square garden is 9 feet, we can calculate the perimeter:
Perimeter = 4 * 9 = 36 feet
Therefore, Ariel will need 36 feet of fencing, so the correct answer is C) 36 ft.
