To find this, you have to cut the figure into familiar shapes. In this case, you can cut it into two rectangles. When you cut it, there is a missing measurement, which is the length for the small rectangle. To find that, you subtract the other two lengths given, which is 8 and 6, and thats the length for the small rectangle. Then you do l•w for both shapes.
