20/16 = h/12;
Cross multiply: 16 x h = 20 x 12
h = 20 x 12/16 = 240/16 = 15 in
To cast a 19 foot shadow the building would have to be 26.91 feet tall. Each foot of building/tree casts 8.47 inches of shadow.
A stick is 6/4.5 = 4/3 times its shadow. So the tree is 4/3*25 = 33.3... feet or 33 ft 4 inches tall.
A 1 foot shadow I think.
The height of the tree is in direct proportion to the pole and its shadow
It works out as: 42.353 feet tall rounded to 3 decimal places
60 inches, or 5 feet.

It sounds like a homework question, so I am going to act like a tutor. What you need to do is convert the height of the building and the shadow into inches. Fifty three feet three inches is equal to how many inches? 30 feet is equal to how many Inches? Then all you have to do is figure out the ratio (larger number divided by smaller number in this case) and multiply that by the height of the shadow of the man) Then you might want to convert back into feet and inches. Hint: the building is taller than its shadow, so the man also will be taller than his shadow.
