Question 288257: A trapezoid has a lower base which is twice as long as its parallel upper base. The upper base is 17 cm long. One non-parallel side is 12 cm long and the other non-parallel side is 6 cm longer than the shorter non-parallel side. What is the perimeter of the trapezoid?

Hello,
Since we know the one side is 17 the lower base is 34 and we can add the other 2 sides which are 12 and 18 so:
17+34+12+18=81 cm
Make sense?
