For the first question, since the perimeter of rectangle ABCF is 34, the side + length = 17. 17 - 10 = 7. So AF = BC = 7. 12 - 7 = 5. Trapezoid area = 1/2(b1 + b2) * h. (6 + 10)/2 * 5 = 40. 40 is your answer for the first question.

For the second question, 150 - 50 - 16 = 100 - 16 = 84. 84 is your answer for the second question.
