Find the area of trapezium whose parallel sides are 20 cm and 18 cm long, and the distance between them is 10 cm.  Choose the correct choice from the following options:
A) 287 cm2  B) 190 cm2  C) 180 cm2  D) 785 cm2  E) 295 cm2
Explanation:   Area of a trapezium = 1/2 (sum of parallel sides) * (perpendicular distance between them) = 1/2 (20 + 18) * (10) = 190 cm2   Answer: Option 190 cm2
