The telephone pole is $6$ meters tall.
We can set up a proportion that compares a meter stick and its shadow with a telephone pole and its shadow: $\frac{1}{1.5} = \frac{x}{9}$ Use the cross products property to eliminate the fractions: $1.5x = 9$ Divide each side by $1.5$ to solve for $x$: $x = 6$ m The telephone pole is $6$ meters tall.
