Some common sense of Mount Tai, how high is Mount Tai? What's the difference between altitude and altitude?

The official elevation of Mount Tai 1545 meters is the value engraved on Jade Emperor Peak, the main peak of Mount Tai. Some versions are similar in altitude, because crustal movement and altitude error are inevitable.

The question is why the altitude is 1545 meters and the distance from the foot of the mountain to the top of the mountain is 9000 meters, which is so different from the official altitude. So I made a picture here to see:

The red line represents the altitude, and the purple line represents the distance from the foot of the mountain to the top of the mountain. According to the definition of triangle, the distance will definitely be much larger than the height map.

Mount Tai is famous for its magnificent scenery. Overlapping mountains, heavy bodies, the contrast between pine trees and boulders, and the change of clouds make it bright, magnificent and magical. The natural Mount Tai shows the magic of nature; The Mount Tai of culture proves the sacredness of culture. Mount Tai is the symbol of the Chinese nation, the epitome of splendid oriental culture, the place where the idea of "harmony between man and nature" is entrusted, and the home of the Chinese national spirit.
