O · · · ·
Given:
Both endpoints share y = 0.
To Find:
The width.
Formula:
Horizontal length is | − |.
Solution:
Width = |11.5 − 8| = 3.5 ft.
This is the geometric opening. Actual ease of access also depends on clear space, door swing and the user’s needs; the sketch alone cannot guarantee it.
Results:
The model gives a 3.5 ft opening.
