Marco's teacher challenges him to find and plot all possible pairs of $(w, l)$, with $w$ as the width and $l$ as the length, where both are positive integers and they form a rectangle with an area of 18 square units. How should Marco plot these pairs?
A) (1, 18), (2, 9), (3, 6), (6, 3), (9, 2), (18, 1)
B) (1, 18), (2, 7), (4, 4.5)
