Answer 2

Calculation of the Height of the Lantern

To calculate the height of the lantern, we can use similar triangles. Let's assume that the height of the lantern is h.

Given: - The person's height is 1.5 meters. - The person is standing 10 steps away from the pole. - The person's shadow is 6 steps long.

We can set up the following proportion:

Person's height / Person's shadow = Height of the lantern / Distance from the person to the lantern

Using the given values, we can substitute them into the proportion:

1.5 meters / 6 steps = h / 10 steps

To solve for h, we can cross-multiply and then divide:

1.5 meters * 10 steps = 6 steps * h

15 meters = 6 steps * h

h = 15 meters / 6 steps

Simplifying the expression:

h = 2.5 meters

Therefore, the lantern is located at a height of 2.5 meters.
