<em>x</em>² represents the area of the original sheet of wrapping paper.  This would be a square that is <em>x</em> units long and <em>x</em> units wide.  11<em>x</em> 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 <em>x.  </em>The area of a rectangle is given by width * length; in this case 11*<em>x</em> or 11<em>x</em>.
The expression she has, <em>x</em>² - 11<em>x</em>, represents the area of the sheet of wrapping paper after she's cut it.<em />

Answer:

The correct option is 1. It means 11x is the area cut from the sheet of wrapping paper.

Step-by-step explanation:

The shape of sheet is square.

Let  x represents the length, in centimeters, of the sheet of wrapping paper before being cut.

The area of a square is

A=a\times a

Where, a is side length.

The area of sheet before being cut is

A=x\times x=x^2

The width of the piece cut from the sheet is 11 and length is x. So, the area of piece is

A=x\times 11=11x

The remaining area of sheet is

A=\text{Area of sheet}-\text{Area of piece cut from the sheet}

A=x^2-11x

Therefore correct option is 1. It means 11x is the area cut from the sheet of wrapping paper.
