Find the area of trapezium whose parallel sides are 20 cm and 18 cm long, and the distance between them is 14 cm	Choose the correct option.
A) 178 cm2 B) 179 cm2 C) 266 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) * (14)   = 266 cm2   Answer: 266 cm2
