Find the distance between two parallel sides if `AB||CD`.

The area of a trapezium is 279 sq. cm and the distance between its two parallel sides is 18 cm. If one of its parallel sides is longer than the other side by 5 cm, find the lengths of its parallel sides.

If the lengths of the two parallel sides of a trapezium are 5 cm and 7 cm and the distance between these parallel sides is 4cm. Find its area (in cm^(2) ).

If the lengths of the two parallel sides of a trapezium are 8 cm and 10 cm and the distance between these parallel sides is 6 cm. Find its area (in cm^(2) ).

Each side of a rhombus is 18 cm. If the distance between two parallel sides is 12 cm, find its area.

The area of a trapezium is 105cm. If one of the parallel sides is 28 cm and the distance between the parallel sides is 5 cm, find the length of the other parallel side.

The area of a trapezium shaped field is 480 m^2 , the distance between two parallel sides is 15 m and one of the parallel side is 20 m. Find the other parallel side.
