Question
The lengths of a pair of parallel sides of a trapezium
are respectively 22 cm and 18 cm, and the perpendicular distance between these two sides is 15 cm. What is the area (in cm²) of the trapezium?Solution
According to the question Area of trapezium = 1/2 x sum of its parallel sides x perpendicular distance between parallel sides 1/2 x (22 + 18) x 15 cm² = (1/2 x 40 x 15) cm² = (20 x 15) cm² = 300cm² The area of the trapezium is 300 cm².
