Find the area of trapezium whose parallel sides are 20 cm and 18 cm long, and the distance between them is 17 cm  Pick one.
A) 178 cm2  B) 323 cm2  C) 285 cm2  D) 167 cm2  E) 197 cm2
Area of a trapezium = 1/2 (sum of parallel sides) * (perpendicular distance between them)   = 1/2 (20 + 18) * (17)   = 323 cm2   Answer: 323 cm2
