Respuesta :

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

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
