Edit: This method here is correct, you just need to double the answer
The area for a right angle triangle is B*H divided by two. But since there's two of the same triangle, if they were put together they'd make a rectangle.
The only method that I found that has the answer as one of the choices is:
\(7*9.5=66.5\)
\(12*9.5=114\)
\(114+66.5=180.5\)
180.5 Square inches
Hope this helps ;P
Another method used was the 1/2*b*h:
\(1/2*7*9.5= 33.25\)
\(1/2*12*9.5 = 57\)
Then add the two:
\(57+33.25= 90.25\)
You get the same answer of 90.25 square inches
But then you asked the same question, and you got a different response:

If you were to substitute your answers with the ones in the formula, it would look like:
\((1/2) (9.5)(12+7)\)
\((1/2)(9.5)(19) = 90.25 \)
So it would be 90.25 square inches
The formula CPhill used
Right because they are different nuumebers. Just substitute the numbers here with that formula.
Thsi question has already been answered similarly:
https://web2.0calc.com/questions/an-artist-is-designing-a-kite-like-the-one-show-below
You could use the same formula that was shown, just with your numbers instead.
