For this case we have a figure composed of a trapezoid and a triangle.
By definition we have that the area of a trapezoid is given by:

Where:
B: It's the biggest side
b: It is the minor side
h: It's the height.
So:

For its part, the area of a triangle is:

Where:
b: It's the base
h: It's the height

Thus, the total area is the sum of the two areas:

ANswer:
