To find the height of the flagpole, we can use the concept of similar triangles. Since the flagpole and Patrick cast shadows under the same conditions, the ratios of their heights to their shadow lengths will be equal.

Given:
- Patrick's height: 1.5 meters
- Patrick's shadow: 1 meter
- Flagpole's shadow: 4.5 meters

Let \( h \) be the height of the flagpole. The ratio can be set up as follows:

\[
\frac{\text{Patrick's height}}{\text{Patrick's shadow}} = \frac{\text{Flagpole's height}}{\text{Flagpole's shadow}}
\]

\[
\frac{1.5}{1} = \frac{h}{4.5}
\]

Now, solve for \( h \):

\[
h = 1.5 \times 4.5 = 6.75 \text{ meters}
\]

Therefore, the height of the flagpole is 6.75 meters.

Suppose a flagpole casts a shadow 4.5 m long. Patrick is standing near the pole. He is 1.5 m tall and his shadow is 1 m long. How tall is the flagpole?
