final size of the parts used in the model will be 40 times smaller, and the actual size of the boat will be 60 centimeters
Reasoning is tgis; real boat is 22 meters long....one tenth of that will be 2.2 meters....one 20th would be half of that, or 1.1 meters, one half of thata would be 55 centimeters (which is 1 fortieth on 22 meters........)
So the answer is 55 centimeters

I think you are looking for what size will the model be. If so the 1:40 is the scale. If the size of the real boat is 22 meters, than the model will be .55 meters. (22 / 40)

Length of model = 22 x 1 / 40 x 100 cm
= 2200 / 40 cm
= 220 / 4 cm
= 55 cm

model : real
1 : 40
? : 22
the model = ( 1 x 22 ) / 40 = 0.55 m
= 0.55 x 100 = 55 cm
