Kendrick Buck · Answer 1

x² represents the area of the original sheet of wrapping paper. This would be a square that is x units long and x units wide. 11x would be the area of the section she cut off; she cut off 11 cm from the width, so the width of the piece cut off is 11, and the length of the piece she cut off is still x. The area of a rectangle is given by width * length; in this case 11*x or 11x.

The expression she has, x² - 11x, represents the area of the sheet of wrapping paper after she's cut it.
