What is the perimeter of a trapezoid with bases of length 11 and 6, and sides of length 12 and 8?

  1. 39

  2. 48

  3. 42

  4. 36

The correct answer is: 39

A trapezoid is a quadrilateral with only two parallel sides. This means that the top and bottom sides, or the bases, are parallel and the other two sides are not. In order to find the perimeter of a trapezoid, we must add up all four sides. In this case, the top and bottom sides have lengths of 11 and 6, and the other two sides have lengths of 12 and 8. Adding all of these together gives us a perimeter of 37. Option B is incorrect because it only adds together two of the sides, while option C does not account for the length of the bases. Option D is incorrect because it adds together all four sides, but does not have the correct sum. Therefore, the correct answer is A.
