Let's set up an equation to express the perimeter of the rectangular garden in terms of the width (W).
The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, we have two equal lengths and two equal widths.
Let's denote the width as W. According to the problem, the length is 5 feet less than twice the width, which can be expressed as (2W - 5).
To calculate the perimeter, we add the lengths of all four sides:
Perimeter = 2 * length + 2 * width
Substituting the values for length and width:
Perimeter = 2 * (2W - 5) + 2 * W
Simplifying the equation:
Perimeter = 4W - 10 + 2W
Perimeter = 6W - 10
Therefore, the equation expressing the perimeter of the rectangular garden in terms of W is:
Perimeter = 6W - 10
This equation relates the width (W) to the total perimeter (320 feet) of the rectangular garden.
