**Steve**, Thursday, September 29, 2011 at 5:25amTo avoid confusing l and 1, I'll use L and W.

L is the total page length

W is the total width

Area = LW = 100

Let L' be the printable length, W' the printable width.

L' = L - 2*1 = L-2

W' = W - 2*1.5 = W-3

The printable area has margins top and bottom, and right and left. So, the printable area P is

P = L'W' = (L-2)(W-3)
