What is the smallest acceptable area of one poster, rounded to the nearest thousandth of square inch?

Given:

poster standard dimension: 8 1/2 inches by 11 inches

length and width may vary 1/20 %

1/20 % convert in decimal form: 0.05% or 0.0005

Area = 8 1/2 inches * 11 inches = 93.5 sq. inches

Smallest acceptable area for one poster:

Width: 8.5 inches * (1 - 0.0005) = 8.49575

Length: 11 inches * (1 - 0.0005) = 10.9945

Area = 8.49575 * 10.9945 = 93.4065 or 93.407 sq. inches.
