The following is a 1:1000 scale vegetable plot plan, calculate its actual area The vegetable field is trapezoidal, the top is 2 cm, the bottom is 2.5 cm, and the height is 2.5 cm

Area = (upper bottom + lower bottom) * height / 2 = 5.625 square cm
Actual area = 5.625 * 1000 * 1000 = 5625000 square centimeters = 562.5 square meters
