you split the shape into two rectangles and then find the missing side lengths and then you can find the area of each rectangle and add them up. i did a vertical line on the left side of the extra piece so then you would have two rectangles rectangle 1= 5x5 and rectangle 2= 2x6. then you find the area of each- 5x5=25 and 2x6=12. 25+12= 37 so the AREA=37
