Thank you for the opportunity to help you with your question!

5.5 meter tall worker casts a shadow of 4 feet long. Lets say x meter long utility pole casts a shadow of 20 feet long, then we have proportion

5.5/x=4/20

solving for x

5.5/x=1/5

x=5.5*5=27.5 feet

So height of utility pole is 27.5 feet.
