In order to solve this we need to know which number, 6, 4.8 or 3.5 represents the height of the walls. So I cannot find the answer for you. But I can show you how to find it yourself, once you figure out which is the height.

The room has four walls. Because of the rectangles involved, the opposite walls will be congruent to each other.

If...
l = length of the room
w = width of the room
h = height of the room
... then the areas of the four walls will be:
lh + wh + lh + wh
which simplifies to:
2lh + 2wh
Now just replace the l, w and h with the right numbers and simplify.
