On the drawing with a scale of 1:500, the side length of a square flowerbed is 4cm. How many square meters is the actual area of the flowerbed? Why is the actual area: 20 * 20 = 400 square meters instead of side length * 4, that is, 20 * 4 = 80

On the drawing with a scale of 1:500, the side length of a square flowerbed is 4cm. How many square meters is the actual area of the flowerbed? Why is the actual area: 20 * 20 = 400 square meters instead of side length * 4, that is, 20 * 4 = 80

The actual side length is: 500 * 4 = 2000 cm = 20 m
The actual area of this flower bed is: 20 * 20 = 400 square meters
