A book is 6 inches wide and 9 inches tall. A rectangle is shown. The length of the rectangle is labeled 6 inches. The width of the rectangle is labeled 9 inches. A publisher wants to use a scale factor of 1.5 to enlarge a book. What will the area of the front of the book be after the book is enlarged? 54 in2 81 in2 121.5 in2 78.75 in2

Respuesta :

 The first step is to enlarge 6 inches.   6 inches enlarged by 1.5 = 9 inches
 Then 9 inches.                                  9 inches enlarged by 1.5 = 13.5 inches


 Next, you multiply to find the area.    area = 9 × 13 = 121.5 square inches

The area of the front of the book be after the book is enlarged is 121.5 inches.

Given the following data:

  • Length of rectangle = 9 inches
  • Width of rectangular field = 6 inches
  • Scale factor = 1.5

To calculate the area of the front of the book be after the book is enlarged:

First of all, we would determine the new dimensions (length and width) of the book after it is enlarged.

[tex]New \;length = 1.5 \times 9[/tex]

New length = 13.5 inches.

[tex]New \;width = 1.5 \times 6[/tex]

New width = 9 inches.

Formula for the area of a rectangle.

Mathematically, the area of a rectangle is given by the formula;

[tex]A=LW[/tex]

Where:

  • A is the area of a rectangle.
  • L is the length of a rectangle.
  • W is the width of a rectangle.

Substituting the parameters into the formula, we have;

[tex]A = 13.5 \times 9[/tex]

A = 121.5 inches.
