ACT math section. Just need a little help to solve this. I know the answer I circled is wrong.

Answer:
B. 60.5
Step-by-step explanation:
You have 2 main shapes, a trapezoid and a triangle.
Extend the left leg of the triangle all the way up.
How we have a trapezoid with bases of 14 and 10, with a height of 3. The are of the trapezoid is
A = (1/2)(sum of bases)(height) so we have
A = (1/2)(10 + 14)(3)
A = (1/2)(24)(3)
A = 36
We are told the triangle is a 45°-45°-90°, so the legs are equal, that makes the area
A = (1/2)(7)(7) = 49/2 = 24.5
The total area is 36 + 24.5 = 60.5 units²
