Question

    The lengths of a pair of parallel sides of a trapezium

    are respectively 21 cm and 17 cm, and the perpendicular distance between these two sides is 11 cm. What is the area (in cm²) of the trapezium?
    A 627 Correct Answer Incorrect Answer
    B 104.5 Correct Answer Incorrect Answer
    C 418 Correct Answer Incorrect Answer
    D 209 Correct Answer Incorrect Answer

    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 (21 + 17) x 11 cm² = (1/2 x 38 x 11) cm² = (19 x 11) cm² = 209 cm² The area of the trapezium is 209 cm².
