Answer:
To solve this problem you can divide the figure is known figures that have exact formulas for calculate their areas. As you can see in the figure attached, you can divide in two trapezoids, one rectangle and two right triangles. Therefore, you have:
Area=((4+3)6)/2+((6+3)5)/2+(3x1)+(3x4)/2+(3x3)/2
Area=21+22.5+3+6+4.5
Area=57
The answer is: The area is 57
