A Trapezium
| The difference between the parallel sides of a trapezium is 10 cm. The distance between the parallel sides is less than the shorter side. The area is 561 cm2. All measurements are integer values. |  |
Note that trapezium here is given the British meaning. For U.S. residents, you can substitute the word trapezoid.
What are the lengths of the two parallel sides, and what is the distance between them?
