Find the area of trapezium whose parallel sides are 30 cm and 12 cm long, and the distance between them is 16 cm?
Choose the most appropriate option:  A) 288 cm2  B) 277 cm2  C) 285 cm2  D) 336 cm2  E) 340 cm2
Area of a trapezium = 1/2 (sum of parallel sides) * (perpendicular distance between them)   = 1/2 (30 + 12) * (16)   = 336 cm2   Answer: 336 cm2
