The usual form for the area of a trapezoid is (average of the parallel sides) x height.
If only the lengths of the sides are given, then calculation of the area requires trigonometry and multiple solutions are possible.
Often, teachers will give a problem like this showing the two unequal parallel sides and two unequal, non-parallel sides with a diagram showing that one of the sides is perpendicular to the parallel sides. That side length would be the height.

Does trapezium have parallel sides?
A trapezium has two parallel sides (of unequal length) and two non-parallel sides.
How many parallel sides does the trapezium have?
A trapezium has only one pair of parallel sides
What are the characteristics of a trapezium?
has two parallel sideshas four straight linesThe area of the trapezium is given by the following formula where a and b are the lengths of the parallel sides and h is the perpendicular distance between the parallel sides.
What is the formaula for the area of a trapezium?
If the two parallel side of the trapezium are a and b and height of the trapezium (the distance between the parallel sides) is h then the area is given by:Area = 1/2 (a + b) x hHalf the sum of the lengths of the parallel sides times the distance between them.
Does a trapezium have any equal sides?
It can do. The non-parallel sides of an isosceles trapezium will be equal. Also, one of the non-parallel sides could be equal to one of the parallel sides.
