Perimeter of a rectangle
2L means two sides of length, thus multiply
2W means two sides of width; again multiply
four sides around the rectangle and adding the L and W values gives the perimeter.
Example:
You have a rectangle that is 10 feet long and 6 feet wide. Find perimeter of rectangle that has 4 sides.
Perimeter = 2(10 feet) + 2(6 feet)
P = 20 feet + 12 feet
Perimeter = 32 feet
the formula is: l = length w = width 2l + 2w
22
You'd just add all the sides up so if you wanted a formula for it it'd be 2L + 2W = permitter
The formula for perimeter of a rectangle is: P=2L+2W where L is the length and W is the width of the rectangle.
Since the formula for the perimeter of a rectangle is 2 times the lenght plus 2 times the width (P = 2l + 2w). P = 2(8) + 2(3) P = 16 + 6 P = 22m
P = 100 l = 30 w = 20
2L+2W=P (S2w) Subtract 2W from both sides 2L=P-2W (D2) Divide both sides by 2 L=(P-2W)/2
Oh honey, solving for w in 2l + 2w = P is as easy as stealing candy from a baby. Just subtract 2l from both sides and then divide by 2. Voila, w = (P - 2l) / 2. Now go show off your math skills like the boss you are.
If you would to solve for (l) then l = 4x/2 + 3/2 (4x + 3 is over 2).To solve for x. x = 2l/4 + 3/4 ( 2l + 3 is over 4)Hope this helps.
a = L x W: area equals length times the width. p = 2L + 2W: perimeter equals 2 times the length plus 2 times the width so L = (p - 2W)/2
There is no indication as to what B represents and consequently no possibility of answering the question.
A little more info would be nice but as it stands your equation is 2L + C = P
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals". There is no operator between P and 2L.
P=2w+2l
For a rectangle, P = 2L + 2W (L is length, W is width)
the formula is: l = length w = width 2l + 2w
