A sheet of paper is 8 1/2 in wide and 11 in long. The sheet is printed with a margin 1 1/4 in. wide on all four sides. Find the perimeter of the printed part of the page.
I got 34; I subtracted 11 with 1 1/4 and 8 1/2 with 1 1/4. I got 9 3/4 and 7 1/4. I added those and got 17, then I doubled it and got 34.
Here is the simpler version
W= 8.5 - 2 x 1 1/4 (using PEMDAS) = 8.5 - 2.5 = 6
L= 11 - 2 x 1 1/4 (using PEMDAS) = 11 + 2.5 = 8.5
P= 2 x (6+8) = 2 x 14.5 = 29
Dang I just saw this bc I got this as my math homework and they did this all the way in August 2014 XD when it is now September 2021.
I wonder where they are in life now.
no, you have to subtract the margin on both sides, and top and bottom
W=8.5-2(1 1/4)=8.5-2.5=6
L=11-2(1 1/4)=11-2.5=8.5
P=2(6+8.5)2*14.5=29 check that
I just looked it up and there are so many people with that name
YALL I DIDN'T MEAN TO PUT (6+8) I MEANT TO PUT (6+8.5)
To find the perimeter of the printed part of the page, you need to consider the dimensions of the area without the margins. Let's break down the steps:
1. Begin with the dimensions of the sheet: 8 1/2 inches wide and 11 inches long.
2. Determine the dimensions of the printed area by subtracting the margin from each side. In this case, the margin is 1 1/4 inches on all four sides.
- Subtract 1 1/4 inches from the width: 8 1/2 - 1 1/4 = 7 1/4 inches.
- Subtract 1 1/4 inches from the length: 11 - 1 1/4 = 9 3/4 inches.
3. Find the perimeter of the printed area by summing the lengths of all four sides:
- Add the two lengths: 7 1/4 inches + 7 1/4 inches = 14 1/2 inches.
- Add the two widths: 9 3/4 inches + 9 3/4 inches = 19 1/2 inches.
4. Finally, find the overall perimeter by adding the calculated lengths of the sides:
- Perimeter = 14 1/2 inches + 14 1/2 inches + 19 1/2 inches + 19 1/2 inches = 67 inches.
Therefore, the perimeter of the printed part of the page is 67 inches, not 34 inches.
