Let b and t be the lengths of each parallel side. Let A=187 for area. Let h=22 for height. Let b=6, for one of the parallel sides so that t is unknown.

, so that the average of the two bases will be used.

The area of a trapezoid is 187 cm squared. The height is 22 cm and the length of one of the parallel side is 6 cm. Find the length of the other parallel side.
***
area of a trapezoid=h/2(a+b), h=height, a=one of the parallel sides, b=other parallel side
(22/2)(a+6)=187
11a+66=187
11a=121
a=11
length of the other parallel side=11
