Take into account that the scale of the drawing realted to the actual size is
2 cm = 2.5m
Conisder that the width and length of the living space is 16.8 cm and 4.8 cm respectivley.
Convert the height and length to the actual lengths by using the given scale, as follow:
length = 16.8 cm => 16.8 (2.5 m) = 42 m
height = 4.8 cm => 4.8 (2.5 m) = 12 m
Hence, the actual length of the living space is 42 m
