Question 825304
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.<br>
The room has four walls. Because of the rectangles involved, the opposite walls will be congruent to each other.<br>
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.
