As shown in the figure, a large rectangle is just divided into six small squares, of which the smallest square area is 1 square centimeter, then the area of the large rectangle is () A. 154 square centimeter B. 143 square centimeter C. 132 square centimeter D. 120 square centimeter

Because the area of the small square is 1 square centimeter, the side length of the small square is 1 centimeter. Let the largest side length of the six squares be x centimeter. Because the smallest side length of the square in the figure is 1 centimeter, the side lengths of the other squares are X-1, X-2, x-3, x-3, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp
