Find the area of trapezium whose parallel sides are 10 cm and 18 cm long, and the distance between them is 15 cm.  Choose the correct option: A) 287 cm2 B) 785 cm2 C) 285 cm2 D) 785 cm2 E) 210 cm2
210 cm2xplanation:   Area of a trapezium = 1/2 (sum of parallel sides) * (perpendicular distance between them) = 1/2 (10 + 18) * (15) = 210 cm2   Answer: Option 210 cm2
