First we will convert all the units in terms on centimetre
actual height of chimney = 12m = 12*100= 1200 cm
actual height of the factory= 28m = 28*100= 2800cm
ratio of height of model chimney to height of actual chimney = 9/1200
= 3/400
height of model factory= ratio of height of model chimney to height of actual chimney* height of actual factory
=3/400*2800
=21cm or 0.21m
