The answer is 54 square units.
First, you can break the figure up into four parts. Three triangles, and one square. The first triangle is right triangle, with legs 3 units and 4 units. to find the area, multiply both legs and divide by two. That should be 6 square units. Then you should do the same with the next two right triangles. You should get 9 square units for legs 3 and 6, and get 3 square units for legs 6 and 1. Dont forget the 6x6 square, which should have area 36. Add 6+9+3+36= 54.
