The calculation formula of land mu is 1 mu =60 abbots = 6000 square feet, 1 mu =666.667 square meters. Generally, this value is not needed to calculate the number of mu, which is more troublesome, but a simpler calculation method is needed.

The formula is: length (m) × width (m) ×0.00 15= mu. For example, the land area with a length of 200m and a width of 150m is 200 (m )×150 (m )× 0.0015 = 30,000 square meters× 0.0015 = 45 (mu).

If the land is in a regular shape, the land area mu = length m× width m×0.00 15, or the land area mu = length m× width m/666.67. The specific measurement of the length and width of the field can be carried out by methods such as rope ruler, or you can download a measurement app, such as an acre of rice, and walk around the field to measure the length and width.

The importance of learn mathematics:

1. Mathematics is closely related to our life. To say that the real effect of learning mathematics is not reflected in exam-oriented education, but in my own thinking about the future.

2. The importance of mathematics is self-evident. Mathematics is the foundation of all sciences and an important channel to cultivate logical thinking. It can be said that every major progress of our mankind is strongly supported by mathematics.

3. The application of mathematical knowledge in life is everywhere. From the calculation of daily living costs, to astronomy, geography, quality control, agricultural economy, aerospace, there are shadows of using mathematics.
