Tiantan Park is a famous park in China. It is a place where the royal family sacrificed to heaven and earth and prayed for a bumper harvest in Ming and Qing Dynasties. Covering an area of about 2.73 million square meters, it may bring some intuitive feelings to people.

First of all, we can compare this area with some common places. For example, the area of Tiantan Park is about the size of 300 standard football fields. If schools or buildings are taken as reference objects, and the main building in Tsinghua University is taken as an example, assuming that it covers an area of about 200,000 square meters, the area of Tiantan Park is equivalent to the size of Tsinghua University 13 main building.

In addition, Tiantan Park has a long history, which was founded in Yongle period of Ming Dynasty and has a history of nearly 600 years. It consists of a series of temple buildings and square landscapes, including Mouqiu, Hall of Praying for the New Year, Echo Wall and other famous scenic spots, attracting a large number of tourists. Therefore, Tiantan Park is not only a place with historical and cultural background, but also a place to enjoy the natural landscape and experience the traditional culture of China.

In addition, this area data can also help us better understand the position and role of Tiantan Park in Beijing. Beijing is the capital of China, and it is also a densely populated city with limited land resources.

In such a city, being able to retain such a large area of parks fully reflects the importance that the government and society attach to ecological protection and people's quality of life. At the same time, the existence of Tiantan Park has also made important contributions to Beijing's urban planning and ecological balance.

Algorithm of floor space:

1. Calculation of rectangular area: First of all, the park land can be approximately regarded as a rectangle, so the occupied area is the length times the width. But this method may not be accurate in practice, because the land in the park is often not a completely regular rectangle.

2. Consider buildings and vegetation: In order to calculate the area of Tiantan Park more accurately, we need to consider the buildings and vegetation in the park. Buildings, such as Hall of Praying for the New Year, Mouqiu altar, etc. , can be measured by satellite map. Vegetation area can be obtained by measuring the area covered by lawns, lakes and other plants. Add up these areas and you can get the total area of Tiantan Park.

3. Consider terrain and roads: When calculating the area of Tiantan Park, you also need to consider the terrain and roads in the park. For example, lakes and hills in the park may occupy a certain area, and roads will also occupy a certain space. In order to calculate the area more accurately, it is necessary to take these landforms and road areas into account.
