Find the area of trapezium whose parallel sides are 20 cm and 18 cm long, and the distance between them is 13 cm. Choose one: A) 335 cm2 B) 885 cm2 C) 285 cm2 D) 247 cm2 E) 725 cm2
Area of a trapezium = 1/2 (sum of parallel sides) * (perpendicular distance between them)   = 1/2 (20 + 18) * (13)   = 247 cm2   Answer: 247 cm2
