Each picture has a perimeter of 2(4+6) = 20 inches and an area of 4x6 = 24 square inches.
Since Julie has four pictures, the total perimeter covered by the pictures is 4 x 20 = 80 inches.
The total area covered by the pictures is 4 x 24 = 96 square inches.
Therefore, the pictures will cover 80 + 96 = 176 square inches of Julie's door.
