Find the area of trapezium whose parallel sides are 20 cm and 10 cm long, and the distance between them is 10 cm.	Choose the correct choice:
A) 187 cm2 B) 185 cm2 C) 150 cm2 D) 185 cm2 E) 195 cm2
Explanation:   Area of a trapezium = 1/2 (sum of parallel sides) * (perpendicular distance between them) = 1/2 (20 + 10) * (10) = 150 cm2   Answer: Option 150 cm2
