Matheng
Poster standard dimension: 8.5 inches by 11 inches
Both length and width of the poster may vary 1/20%
∴ length and width may vary 1/20 % = 0.05% = 0.0005

∵ Area  = Width * Length
∴ Area = 8.5 * 11 = 93.5 in²

Smallest acceptable area for one poster:

Width: 8.5 * (1 - 0.0005) = 8.49575 in.
Length: 11 * (1 - 0.0005) = 10.9945 in.

∴ The smallest area = 8.49575 * 10.9945 = 93.4065 ≈ 93.407 in².
