The area of a trapezium is 45 cm2

and the perpendicular distance
between its parallel sides is 5 cm. If the length of one of its parallel sides is
6cm, find the length of the other parallel side.

       When finding the missing length for a trapezium, you must multiply each side by the variable and divide each side by the height of the triangle by the angle sine.

Hope this helps.
