A rectangular garden that is W ft wide is enclosed by 120 ft of fencing.

How long is the garden?

L= (60-W)

What is the value of W? In other words, how wide is this garden?

To find the length of the garden, we will use the formula for the perimeter of a rectangle. The perimeter of a rectangle is given by the formula P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.

In this problem, we are given that the width of the garden is W ft and the perimeter is 120 ft. We can substitute these values into the formula to solve for the length:

120 = 2L + 2W

To isolate L, we need to first simplify the equation by dividing both sides by 2:

60 = L + W

Now, we can subtract W from both sides to isolate L:

L = 60 - W

Therefore, the length of the garden is 60 - W ft.
