✔ 最佳答案
The total surface area of the land:building 2500m² X4 = 10000m²
garden 30000 m²
So Building + garden = 40000m²
Therefore the length of each side of the plot of land is :
Square root of 40000 = 200

Total Area of the 4 buildings occupied : 4 X 2,500m² = 10,000m²
Area of the square plot of land: 10,000m² + 30,000m² = 40,000m²
Therefore, the length of each side of the plot of land:
=> square root of 40,000m² = 200m
