Find the area of trapezium whose parallel sides are 20 cm and 18 cm long, and the distance between them is 15 cm.
Choose the most appropriate option
A) 287 cm2  B) 785 cm2  C) 285 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) * (15) = 285 cm2   Answer: Option 285 cm2
