To summarize, on the 1:500 scale map, each side of the rectangular parcel of land is represented by 30 cm in length and 20 cm in width.

Therefore, each side of the rectangle on the map is 30 cm long and 20 cm wide.

The width of the rectangle on the map is 10m ÷ 500 = 0.02m (20 cm), using the same scale ratio.

The length of the rectangle on the map is 15m ÷ 500 = 0.03m (30 cm), as each metre on the map represents 500 metres in reality.
