Find the area of trapezium whose parallel sides are 20 cm and 18 cm long, and the distance between them is 15 cm.  Options
A) 335 cm2  B) 885 cm2  C) 285 cm2  D) 825 cm2  E) 725 cm2
Area of a trapezium = 1/2 (sum of parallel sides) * (perpendicular distance between them)   = 1/2 (20 + 18) * (15)   = 285 cm2   Answer: 285 cm2
