Answer:
Option (1)
Step-by-step explanation:
Length of a rectangle = (5.9d + 8.3f) cm
Width of the rectangle = (7.3d + 2.2f) cm
Since formula to get he perimeter of a rectangle is,
Perimeter = 2(length + width)
= 2[(7.3d + 2.2f) + (5.9d + 8.3f)]
= 2(13.2d + 10.5f)
= (26.4d + 21f) cm
Therefore, Option (1) will be the correct option.
The perimeter of the printed part of the page is 29 inches.
<u><em>Explanation</em></u>
Length of the sheet of paper is 11 inches and width is or inches.
Width of the margin is or inches.
As the margin is on all sides of the paper, that means both across the length and width of the paper we need to leave inches for that margin.
So, the length of the printed part inches
and the width of the printed part inches.
Thus the perimeter of the printed part of the page will be: inches.
