Question about Samsung Cell Phones

From the three points you give, the perimeter appears to be the three sides of a triangle going from (9, 7) to (8, -3) to (2, -6) and back to (9, 7).

Or are you actually asking for something else? The length, perhaps? That would be about 31.5 .

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

It varies by the shape. Anything sort of circular usually involves equations with Pi, but objects with corners are different. Since Fixya will not allow me to type equations very well here, I'll refer you to

Add together the lengths of the four sides. Two sides are 4 each and the other two are 10 each, so the total perimeter is 28.

Infinite.

A one meter by 48 meter rectangle has an area of 48 square meters and a perimeter of 98 meters. A one centimeter by 4800 meter rectangle has the same area and a perimeter of 9600.02 meters. A one millimeter by 48,000 meter rectangle has the same area and a perimeter of 96,000.002 meters. A rectangle one micron by 48,000,000 meters has an area of 48 square meters and a perimeter of 96,000,000.000002 meters. Keep making the rectangle skinnier and skinnier without changing the area, and the perimeter keeps getting longer and longer.

This works for any polygon:

Say you have 2 squares - the sides are 5 and 9

Perimeter 1 = 20

Perimeter 2 = 36

20:36 = 5:9

Perimeter 1 = 20

Perimeter 2 = 36

20:36 = 5:9

A square has four equal sides. If the perimeter is 180 yards then each side is 180/4 or 45 yards.

Since a square has four equal sides, the perimeter is four times the length of one side. If a square has a side of 3 metres then the perimeter is 12 metres.

1 tile by 20 tiles - perimeter of 1+ 20 +1 + 20 = 42

2 tiles by 10 tiles - perimeter of 2 + 10 + 2 + 10 = 24

(can't make a rectangle with 3 rows)

4 tiles by 5 tiles - perimeter of 4 + 5 + 4 + 5 = 18

5 tiles by 4 tiles - perimeter of 5 + 4 + 5 + 4 = 18

(can't make a rectangle with 6, 7, 8 or 9 rows)

10 tiles by 2 tiles - perimeter of 10 + 2 + 10 + 2 = 24

20 tiles by 1 tile - perimeter of 20 + 1 + 20 + 1 = 42

So 6 different rectangles. Smallest perimeter is 18.

2 tiles by 10 tiles - perimeter of 2 + 10 + 2 + 10 = 24

(can't make a rectangle with 3 rows)

4 tiles by 5 tiles - perimeter of 4 + 5 + 4 + 5 = 18

5 tiles by 4 tiles - perimeter of 5 + 4 + 5 + 4 = 18

(can't make a rectangle with 6, 7, 8 or 9 rows)

10 tiles by 2 tiles - perimeter of 10 + 2 + 10 + 2 = 24

20 tiles by 1 tile - perimeter of 20 + 1 + 20 + 1 = 42

So 6 different rectangles. Smallest perimeter is 18.

1. Well this one is pretty simple. Since you are not supposed to trim the length trim the width instead.

to make the perimeter 0.4 m shorter cut the cloth by 0.2 m width the picture will make it clear.

2. let the length of rectangle be x cm

and breadth = 20 cm

now original perimeter = 2(x+20) cm

new length = x-30 cm

breadth remains same = 20 cm

new perimeter = 2(x-30+20) cm = 2(x-10) cm

According to question

new perimeter = old perimeter /2

2(x-10) = 2(x+20) /2

2x -20 = x + 20

x = 40 cm

hence length of longer side 40 cm.

Area= width * length

Perimeter= 2 * width + 2* length

Are you looking for an Excel function?

There are no Area or Perimeter functions I am aware of in Excel.
