Question

in trapezium ABCD,AB parallel CD=20cm,AB =10cm and CD=20cm. Find the length of the line segment joining the mid points of AD and BC (give Appropriate reasons)​

Answer 1

Answer:

Correct option is B)

Given AB=12cm , MN=14cm

Since ,segment joining the mid-point of non-parallel sides of trapezium is half the sum of the  lengths of its parallel sides.

⇒MN=21(AB+DC)

14=21(12+CD)

CD=28−12

CD=16cm
