Area of the ceiling: 6*4.5 = 27 square meters
Area of longer wall: 6*4=24 square meters
There are 2 longer walls. So the total area of the longer walls is 24+24=48 square meters.
Area of shorter wall: 4.5*4 = 18 square meters
Again, there are 2 shorter walls. So the total area of the shorter walls is 2*18=36 square meters.
Add up the individual areas to get: 27+48+36=111
So the total area of the ceilings and the 4 walls is 111 square meters.
Now we need to subtract off 14 square meters (since we're NOT going to paint over the windows or the doors) to get 111-14 = 97
So the total area to be painted is 97 square meters.
You did great. You just needed to do that last step.
