The width of the each section on the wall is 403 ft.
Explanation:
The number of picture drawn on the piece of paper.
Also, there is a border on the picture of the same width.
So, the whole page has been divided into FOUR EQUAL PARTS.
Now, the width of the wall = 1612 ft
Let us assume the width of each drawing = k ft
So, 4 x (Width of each part) = Total Width of the wall
So, 4 x ( k ft) = 1612 ft
⇒ K =

⇒ K = 403 ft
Hence, the width of the each section on the wall is 403 ft.
