    Question

    A field is in the shape of a trapezium, where the

    distance between the two parallel sides is 60 metres. One of the parallel sides measures 30 metres, and the total area of the field is 1680 square metres. What is the length of the other parallel side?
    A 26 m Correct Answer Incorrect Answer
    B 33 m Correct Answer Incorrect Answer
    C 36 m Correct Answer Incorrect Answer
    D 32 m Correct Answer Incorrect Answer

    Solution

    Let the length of the other parallel side be 'x' metres.

    Area of trapezium = (1/2) X (sum of parallel sides) X (perpendicular distance between parallel sides)

    Or, 1680 = (1/2) X (30 + x) X 60

    Or, 56 = 30 + x

    So, 'x' = 26 m
