Firstly, we will draw figure
now, we will draw a altitude from B to DC that divides trapezium into rectangle and right triangle
because of opposite sides of rectangle ABMD are congruent
so,
DM=AB=9
CM=CD-DM
CM=18-9
CM=9
now, we can find BM by using Pythagoras theorem

now, we can plug values
we get


now, we can find area of trapezium

now, we can plug values
and we get


so, area of of the trapezoid is
..........Answer
Answer:
This statement is false. The side of a triangle that is opposite an angle greater than or equal to 90° is always the largest side of the triangle.
