We know : A pole is 12 ft and has 4 ft shadow

Meaning it's 3 times less than original (because 12/4 = 3)

And it says if a tree has a 20 ft shadow

Then how high is it actually?

Meaning 20 (shadow) * 3

20*3 = 60

Multiplying since it's about the shadow this time first

Zachery Meza · Answer 2

Since 4*5=20ft, as in the length of the tree's shadow, and 12*5=60, the tree is 60 feet tall.
