Question

     In a trapezium ABCD, AD and BC are parallel to each

    other with a perpendicular distance of 8 m between them. Also, (AD) = (BC) = 10 m, and (DC) = 15 m < (AB). What is the perimeter (in m) of the trapezium ABCD?
    A 25cm Correct Answer Incorrect Answer
    B 42cm Correct Answer Incorrect Answer
    C 62cm Correct Answer Incorrect Answer
    D 18cm Correct Answer Incorrect Answer

    Solution

    Given – DE=CF=8cm DC=EF=15 AD=BC=10 By Pythagoras theorem- AE=FB=6 So, AB=6+15+6=27cm So now perimeter of ABCD=AD+DC+CB+AB =10+15+10+27=62cm
