The figure is composed by two trapezoids.
The formula for calculate the area of a trapezoid is:
Where "B" is the larger base, "b" is the smaller base and "h" is the height.
Let be the area of the figure, the area of the trapezoid on the left and the area of the trapezoid of the right. Then the area of the figure will be:
Substituting values, you get:
