The area of the drafting section on the screen after Jenny left a right margin for editing marks is 1,077,120 pixels.
The first step is to determine the dimensions of the drafting section:
Length = 11 inches
Width = (1 - 1/5) x 8.5 = 6.8 inches
The second step is to convert the dimensions to pixels:
Length = 11 inches x 120 = 1320
Width = 6,8 inches x 120 = 816
Area = 1320 x 816 = 1,077,120 pixels
