On a plan with a scale of 1:400, the bottom of a triangular vegetable field is 8 cm, and the height is 5.5 square On a plan with a scale of 1:400, it is measured that the bottom of a three triangle vegetable field is 8 cm and the height is 5.5 cm. How many square meters is the actual area of this triangle vegetable field?

Bottom = 8 × 400 = 3200 cm = 32 m
Height = 5.5 × 400 = 2200cm = 22m
Area = 32 × 22 × 1 / 2 = 352 square meters
