Find the area of trapezium whose parallel sides are 20 cm and 18 cm long, and the distance between them is 12 cm.
Select the correct option
A) 335 cm2	B) 228 cm2	C) 285 cm2	D) 825 cm2	E) 725 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
