If a 4 ft stick cast a shadow of 2.8 ft. what is the height of a tree that cast a shadow of 27.44 ft?

Height of tree = 39.2 ft

Step-by-step explanation:

The relationship between the height of an object and the length of it's shadow is directly proportional.

So:

h = Height of tree in feet

Cross multiply

2.8h = 4 · 27.44

Simplify

2.8h = 109.76

÷2.8 both sides

h = 39.2

Height of tree = 39.2 ft
