A saw mill cuts boards that are 16 feet long. After they are cut, the boards are inspected and rejected if the length has a percent error of 1.5% or more. The saw mill also cuts boards that are 10, 12, and 14 feet long. An inspector rejects a board that was 2.3 inches too long. What was the intended length of the board?

Convert 16 yards to feet use the conversion rate 3 feet = 1 yard

Bring the fraction a/a-4 to a denominator of 16-a^2
