Answer
To convert the dimensions from feet to metres:
For 11 feet:
11′=11imes30.48extcm=335.28extcm=3.3528extm
For 10'8":
10′8"=10.67imes30.48extcm=326.46extcm=3.2646extm
Thus, the dimensions of the bedroom in metres are approximately 3.35 m x 3.26 m.

Answer
From the problem statement, the scale is given as 1.5 cm representing 3.375 m on the building. To determine the scale:
We express this in the form of 1 : X where X is the number of metres represented by 1 cm on the scale.
1.5extcm:3.375extm=1:(3.375/1.5)extm=1:2.25
Thus, the scale of the floor plan is 1 : 225.
