Are the slanted sides equal in length, i.e. is it an isosceles trapezoid? If so, then you can do this: Draw a line perpendicular to the bases, through the upper corner of the trapezoid that is at the end of the side of length 40. This creates a right triangle with hypotenuse 40, and base equal to (28-24) / 2. Now use the Pythagorean theorem on that right triangle to find the height.
