Sorry this is so late, I had done out all my work a couple minutes after the question was asked but was unable to answer until now due to technical difficulties.
I also got a different number than the other answered, so here's mine:
Area of the small base of the trapezoid:
48*34=1632
Area of the larger base:
62*34=2108
Area of the top and bottom of the figure:
(62+48)/2*40=2200*2=4400
The space on the remaining sides that are covered by the cylinders is made up for by the ends of the cylinders themselves, so it is just
42*34=1428*2=2856
The remaining surface area of the cylinders is 2pi*r*h
2pi*9*26=468pi*2=936pi
Totaling the numbers without pi gets 10996
Add 936pi (about 2940) to that to get 13936
Final answer: about 13936 m^2
Again, sorry the answer is so late, I was unable to submit it earlier.
I just thought I should add my input in case it is needed.
Hope I helped :)
