Shadow - an observation tower

How tall is an observation tower if it casts a shadow 9.6 m long at the exact same moment that a half-metre pole casts a shadow 30 cm long?

Final Answer:

h =  16 m

Step-by-step explanation:

t=9.6 m  a=1/2=21=0.5 m b=30 cm m=30:100  m=0.3 m  h : t = a:b  h=t ba=9.6 0.30.5=16 m
