Answer:
234, don't forget to add the given label
Explanation:
Break down the trapezoid to a triangle and rectangle.
Then find the length of the triangle and use Pythagorean Theorem.
a^2 + 12^2 = 13^2
a = 5, this is the length of the missing side.
Now find the area of the triangle and rectangle and add them together
(5x12/2) + (17x12) = 30 + 204 = 234
