Calculation of the Height of the Lamp Post

To calculate the height of the lamp post, we can use the concept of similar triangles. Let's break down the given information:

- The person's height is 1.5 meters. - The person is standing 16 steps away from the lamp post. - The length of the person's shadow is 4 steps.

We can set up a proportion to find the height of the lamp post:

Person's height / Length of person's shadow = Distance from person to lamp post / Height of lamp post

Let's substitute the given values into the proportion:

1.5 meters / 4 steps = 16 steps / Height of lamp post

To find the height of the lamp post, we can cross-multiply and solve for the unknown:

1.5 meters * Height of lamp post = 4 steps * 16 steps

Height of lamp post = (4 steps * 16 steps) / 1.5 meters

Calculating this, we find that the height of the lamp post is approximately 42.67 meters.

Please note that the above calculation assumes that the person's shadow is proportional to their height and that the lamp post is perfectly vertical.
