Question

A 3,5 m-long stick casts a shadow that measures 5,2 m on the ground what is the height of a flagpole that casts a 29,2 m-long shadow?

Answer 1

since the ratio of height-to-shadow is the same for both objects,

h/29,2 = 3,5/5,2

Now just solve for h.

Answer 2

h/29.2=3.5/5.2
h*5.2=29.2*3.5
5.2h=102.2
5.2h/5.2=102.2/5.2
h=19.65384615
