Question

A flagpole is 35 feet tall. A girl standing nearby who is 4 feet tall casts a shadow that

is 3 feet long. How long is the shadow of the flagpole (at the same time) to the
nearest foot?

Answer 1

26 ft. = the length of the flagpole's shadow to the nearest foot

Explanation:

Let f = the length of the flagpole's shadow

girl's height/flagpole's height = girl's shadow length/flagpole's shadow length

4/35 = 3/f

4f = 105

f = 26.25 ft. ≅ 26 ft = the length of the flagpole's shadow to the nearest foot.
