Find the area of trapezium whose parallel sides are 20 cm and 18 cm long, and the distance between them is 12 cm  Choose the correct choice:  A) 178 cm2  B) 179 cm2  C) 285 cm2  D) 167 cm2  E) 228 cm2
Area of a trapezium = 1/2 (sum of parallel sides) * (perpendicular distance between them)   = 1/2 (20 + 18) * (12)   = 228 cm2   Answer: 228 cm2
