Question
The lengths of a pair of parallel sides of a trapezium
are respectively 12 cm and 20 cm, and the perpendicular distance between these two sides is 14 cm. What is the area (in cm²) of the trapezium?Solution
Area of trapezium = 1/2 x sum of its parallel sides x perpendicular distance between parallel sides 1/2 x (20 + 12) x 14 cm² = (1/2 x 32 x 14) cm² = (32 x 7) cm² = 224 cm² The area of the trapezium is 224 cm².
