Answer: 45.. i think.

Step-by-step explanation: I couldn't really get the measurements from this photo so here is what I got. I used the formula A=a+b over 2 times h. I used 7=a, b=11,h=5. I added 7 and 11 to get 18, then divide that by 2, which equals 9. Then 9 times 5 = 45. I hope this somewhat helps.
