To calculate the width of the garden, we need to use the fact that a rectangle has two sides of equal length opposite each other. Therefore, if the length of the garden is 3 feet, the opposite side must also be 3 feet.
Given that the total fencing available is 24 feet, we can calculate the width using the equation:
Perimeter of a rectangle = 2(length + width)
By substituting the known values into the equation, we get:
24 = 2(3 + width)
Simplifying further,
24 = 6 + 2width
Subtracting 6 from both sides,
18 = 2width
Lastly, we divide both sides by 2 to isolate the width:
width = 18/2
width = 9
Therefore, the width of the garden needs to be 9 feet for it to work.
So, the correct answer is: 9.
