Ashadow 16 meters long is cast by a water tower that is 12 meters tall. if a maypole close by casts a shadow 12 meters long, how tall is the maypole?

The proportion of height-shadow of the two objects is the same.
Make a comparison of height-shadow


In this case, the proportion will be


Plug in the numbers
for an instance, h stands for the height of maypole we want to find.


Do cross multiplication
16h = 12 × 12
16h = 144
    h = 144/16
    h = 9
The height of the maypole is 9 meters
