Wath is formula of a rectangle ?

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.

We are given the following data:

length = 5/2 * width

length = 10 inWe know through the transitive

property of equality that the following must be true:

5/2 * width = 10 in

We then solve this equation algebraically for width:

width = (10 in) * 2/5

width = 4 in

The perimeter of the rectangle is given by substituting our known values of length and width into the following general equation:

Perimeter = 2 * length + 2 * width

Perimeter = 2(10 in) + 2(4 in) = 28 in

In a similar fashion, we substitute these known values into the general equation for the area of the rectangle to solve for the same:

Area = length * width

Area = (10 in)(4 in)=40 in^2

length = 5/2 * width

length = 10 inWe know through the transitive

property of equality that the following must be true:

5/2 * width = 10 in

We then solve this equation algebraically for width:

width = (10 in) * 2/5

width = 4 in

The perimeter of the rectangle is given by substituting our known values of length and width into the following general equation:

Perimeter = 2 * length + 2 * width

Perimeter = 2(10 in) + 2(4 in) = 28 in

Area = length * width

Area = (10 in)(4 in)=40 in^2

Area=width*length

Perimeter=2(l+w)

What combination of two numbers multiplied together equal equal 42? 1*42 / 2*21 / 3*14 / 4*13 / no 5 / 6*7

Add any two sets of numbers and multiply by 2 (l+w).

Very quickly you will see that numbers 6 & 7 are the answer.

It is not common core, but it works without deriving a complex algebraic formula.

Since acre is a measure of area and feet is a measure of distance, you need to calculate the perimeter of a lot with an area of half an acre. Here are the formulas:

1. If the lot is a square (all 4 sides of equal length), multiply the length of one side by 4, to get the # of feet required to walk a half acre piece of land.

2. If the lot is rectangle: (heightx2)+(widthx2).

3. If the lot is a triangle, add up all three sides.

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.

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.

W=L-5 (in inches)

P=2(L+W)=2(L+L-5)=2(2L-5)

Use distirbutive property of multiplication with respect to addition to open up the parentheses (brackets)

P=4L-10.

Set P= 50 (inches), to get 4L-10=50

**Solve for L: Do it'! **

Find W= L (the one you just found) -5 =

Now, with W the value you just calculated

the new length is** L'=-4+3W**

and the new perimeter is** P'=2(L'+W)**

Now your turn to do some work.

Your field, terrain, figure has a particular form. For each form you have a formula that tells you how to compute the area enclosed. Read your book or your notes to know what formula to use. I cannot give you a formula because I have no idea about the shape of the figure nor its dimensions.

Now, having the formula at hand you can use your calculator to calculate the area. But, in order to obtain consistent values you must convert all dimensions to the same unit length: m, cm, km, inches, feet or what have you.

For example: You have a rectangle with LENGTH L=3.5 m, and a width W=20 dm (decimeters), you must convert the value in decimeters to meters, 20 dm=2 m.

The area of you rectangle will be

Area=L*W=(3.5 m)*(2 m)=3.5*2 m*m= 7 m^2
