Question

At the same time that a flagpole casts a 4.5 m shadow , a meter stick casts a 1.5 m shadow. How tall is the flagpole ?

Answer 1

Use a proportion:

1/1.5 = x/4.5

Cross multiply and solve for x.

Answer 2

X=3

Answer 3

A meter stick casts a shadow 1.5 meters long at the same time a flagpole casts a shadow 18 meters long. The triangle formed by the meter stick and its shadow is similar to the triangle formed by the flagpole and its shadow.
