Answer:

The width of the foil = w = 2.5 inches

Step-by-step explanation:

We know that the Area of a rectangular piece:

[tex]A=wl[/tex]

Here:

  • 'w' is the width
  • 'l' is the length

Given that area of the rectangular piece of foil:

Area = A = 11 1/4 square inches

               = 45/4 square inches

               = 11.25 square inches  

                                                                         

Length = l = 4 1/2 inches

                 = 9/2 inches

                 = 4.5 inches

Using the Area formula

[tex]A=wl[/tex]

[tex]w\:=\:\frac{A}{l}[/tex]

    [tex]=\frac{11.25}{4.5}[/tex]

    [tex]= 2.5[/tex] inches

Thus, the width of the foil = w = 2.5 inches
