An expanding rectangle has a fixed width of 7 inches and an initial length of 0 inches. the length of

P = (5.4 inches/sec) t + 14 inches for t > 0

Step-by-step explanation:

A formula for the length of this rectangle is L = (2.7 inches/sec) t, where t is the number of seconds.

The standard formula for the perimeter of a rectangle is P = 2L + 2W.

Substituting  (2.7 inches/sec) t for L, we get:

P = 2( (2.7 inches/sec) t ) + 2(7 inches) for t > 0.

This may be simplified slightly:  

P = (5.4 inches/sec) t + 14 inches for t > 0

(2+2P-2W)/2=L because P and W are numbers you can plug in the equation
[tex]Aformula for finding the perimeter of a rectangle is =2+2 p = 2 l + 2 w . if you know the perimeter[/tex]

[tex]\dfrac{p}{2}-w[/tex]

Step-by-step explanation:

Given : A formula for finding the perimeter of a rectangle is [tex]p=2l+2w[/tex].

To derive the formula for length (l), we first need to subtract 2w on both sides, we get

[tex]p-2w=2l[/tex]

Divide both sides by 2 , we get

[tex]l=\dfrac{p-2w}{2}=\dfrac{p}{2}-w[/tex]

Hence, the formula can you use to find the length (l) =[tex]\dfrac{p}{2}-w[/tex]

Formula one= P = 2 ( l+width) units where

“l” is the length of the rectangle

“b” is the width of the rectangle

Formula 2 = P = 2(l) + 2(w)

Step-by-step explanation:

L=P2-W

Step-by-step explanation:

Step-by-step explanation:

You can first multiply the width by two. Then you subtract that from you perimeter to figure out your length. Whatever number you get divide it by two and there's your length.

Example:

Perimeter =30 Width=5

5 times 2= 10

30-10=20

20/2=10

So your length equals 10.

I hope this helps!

The formula is a fact or a rule written with mathematical symbols. It usually connects two or more quantities with an equal to sign. When you know the value of one quantity, you can find the value of the other using the formula. Examples of formula: Perimeter of rectangle = 2(length + width)
