Tom is a gardener who plants flowers in a rectangular garden. The length of the garden is represented by the variable L and the width by W. If the length is 5 meters longer than the width and the perimeter of the garden is 50 meters, what is the width of the garden?
Recall that the formula for the perimeter of a rectangle is given by:
$$ P = 2L + 2W $$
Using this formula, you can express the relationships in the question.
