Respuesta :
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.
The expression she has, x² - 11x, represents the area of the sheet of wrapping paper after she's cut it.
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
[tex]A=a\times a[/tex]
Where, a is side length.
The area of sheet before being cut is
[tex]A=x\times x=x^2[/tex]
The width of the piece cut from the sheet is 11 and length is x. So, the area of piece is
[tex]A=x\times 11=11x[/tex]
The remaining area of sheet is
[tex]A=\text{Area of sheet}-\text{Area of piece cut from the sheet}[/tex]
[tex]A=x^2-11x[/tex]
Therefore correct option is 1. It means 11x is the area cut from the sheet of wrapping paper.
