Answer:
2 1/8 ft
Explanation:
The distance from the centerline of the picture to its edge is half the width of the picture:
... (10 1/4)/2 = 5 1/8 . . . . feet
The distance from the centerline of the wall to its edge is half its width:
... (14 1/2)/2 = 7 1/4 . . . . feet
When the centerlline of the picture is aligned on the centerline of the wall, the distance from the edge of the picture to the edge of the wall is ...
... (7 1/4 ft) - (5 1/8 ft) = 2 1/8 ft
_____
In inches, this is (2 1/8 ft)×(12 in/ft) = 24 12/8 in = 25 1/2 in.
