Break this up into three rectangles, one big one and two small ones at the bottom. The formula for area is lxw. For the big rectangle, the length is 16 and the width is 16-6. 16x10=160. For the bottom left one, the length is two and the height is six. 2x6=12. For the last one, the length is 4 and the height is 6. 4x6=24. Add them all together 160+12+24=196 square cm
