Nia is building a garden in her yard. She has 24 feet of fencing for her garden and wants it to be in the shape of a rectangle with a length of 3 feet. What does the width need to be for this to work
To find the width of the garden, we need to calculate the perimeter of the rectangle.
Perimeter = 2 * (Length + Width)
Given that the length is 3 feet, we substitute it into the equation:
24 feet = 2 * (3 feet + Width)
Simplifying the equation:
24 feet = 6 feet + 2 * Width
We isolate the width on one side of the equation:
2 * Width = 24 feet - 6 feet
2 * Width = 18 feet
Width = 18 feet / 2
Width = 9 feet
Therefore, the width of the garden needs to be 9 feet for it to work.
