First, draw an isosceles trapezoid with the question information included.

Second, draw an altitude from the top vertex on the left to the bottom, long base, and then do the same on the right top vertex. We have created 2 right (30-60-90) triangles. The height becomes 5sqrt(3) and the long base will become 20; remember that the side opposite the 30 degree angle is 1/2 the hypotenuse of 10 = 5.

Third find the area as
