Answer:

W = field width = 48 ft

Explanation:

Review: the formula for Perimeter of a rectangle is P = 2W + 2L.

Here we're told that the Perimeter is 168 ft. Therefore:

168 ft = 2L + 2W. But we are also told that W = 36 ft. Then:

168 ft = 2L + 2(36 ft) = 2L + 72 ft.

Subtracting 72 ft from both sides, we get 2L = 96, which tells us that:

L = 48 ft.

The field is 48 ft long.
