Greetings! We need to set up a proportion to solve this problem.

So,

the height of the building is unknown x and the height of the statue is 14 feet. The shadows are 48 feet and 5 feet. Then, the proportion states

x/14 = 48/5. We cross multiply to solve for the height x to get 5x = 672. We divide 5 to both sides 5x/5 = 672/5 to get the building being x = 134.4 feet tall.

Hope this helps!
