At a certain time of day, a pole, 5 meters tall, casts a 3-meter tall shadow. the shadow of a building next to the pole is 18 meters long. how tall is the building?

Length of the building = 30 meters

Step-by-step explanation:

Given:

Length of pole = 5 meters

Length of shadow of pole = 3 meters

Length of shadow of the building = 18 meters

To find length of the building.

Solution:

On drawing the figure of the given situation, we get two similar triangles.

Applying proportionality theorem of similar triangles.

Plugging in the given lengths.

Multiplying both sides by 18.

Thus, length of the building = 30 meters
