R is the region in the complex plane that consists of all points z such that each of z/40 and 40/z have real and imaginary parts between 0 and 1 inclusively.

Find the area of R.

(In reply to My region isn't reaching (spoiler) by Steve Herman)

If a is in the range (0,40] and b = 0  wouldn't 40/z be greater than 1? So even that line doesn't fit the criteria.
