Using the trapezoid area formula: Area = (a+b)×h/2 where a=100m, b=60m, h=80m. Area = (100+60)×80/2 = 160×80/2 = 12,800/2 = 6,400 m². Wait, let me recalculate: (100+60)×80/2 = 160×40 = 6,400 m². The correct answer should be A, but based on the given options matching our calculation of 6,400 m², option A is correct.
