In figure, PQRS is an isosceles trapezium. Find x

An isosceles trapezium has all sides equal (b) parallel sides equal non-parallel sides equal (d) any two equal sides

The parallel sides of a trapezium are 40 cm and 20 cm. If its non-parallel sides are both equal, each being 26 cm, find the area of the trapezium.
