im new here and would like an answer to this question for its perimeter and area.
There's something missing in the problem:
There is more than one unlabeled
side, and nothing in the problem tells us that AB and CD have the same length. In the picture as drawn, they are not quite equal, and that means there is no way to find the perimeter from the given information! If you slide BC around, you can get different perimeters.
In your class, is it assumed that "trapezoid" means "
isosceles trapezoid", even if the picture doesn't show that and the words don't say it?
If so, then there is a bit of a trick to find AB and CD, and that is likely to be where you are struggling (assuming you have indeed tried, and aren't just waiting to be
given the answer). Think about what the base of the triangle at the right will be.
Otherwise, perhaps the expected answer for the perimeter is, "Not enough information".
