A square vegetable plot covers an area of 400 square meters. If you draw it on a drawing, the area is 64 square centimeters How to do it?

The so-called scale is:
For example, 1:100000, that is, the length of 1 cm on a map is equivalent to 1000 meters on the spot. Strictly speaking, only on a large-scale map representing a small area, because the curvature of the earth is not taken into account, the scale of the whole map is consistent. Usually, the scale marked on a map is called the main scale, Only some lines or points conform to the main scale. The scale is related to the detail and accuracy of the map content
The formula is: scale = distance on the map / actual distance
400 square meters: 4000000 square centimeters
So the scale is:
64:4000000 - this is the square ratio
At the same time, the prescription obtained:
8:2000
The simplification is as follows:
1:250
