$But check: $ (20 - 1.8076)(15 - 1.8076) = 18.1924 \times 13.1924 \approx 240.0 $.$

Better: use formula: $ x = \frac{35 - \sqrt{985}}{4} $, $ \sqrt{985} = \sqrt{985} $, but final answer expected numerically.
Actually: solve accurately:
Discriminant: $ \sqrt{985} \approx 31.3847 $ → $ x = (35 - 31.3847)/4 = 3.6153 / 4 = 0.9038 $.
So width ≈ 0.904 m. But for exact:
From quadratic: $ x = \frac{35 - \sqrt{985}}{4} $, but since it must be simplified, and value is irrational, use decimal.
But question expects exact form? No — likely decimal.
