Pull the rectangle nailed with wooden strips into a parallelogram, its area () A. Bigger B. smaller C. unchanged

As shown in the figure: pull the rectangle nailed with wooden strips into a parallelogram, then the bottom of the parallelogram is the length of the rectangle, and the height of the parallelogram is shorter than the width of the rectangle, so the area of the parallelogram is less than the area of the rectangle, so choose B
