If the shape is a rectangle, then

Perimeter = 2(Length + Width)

So Width = Perimeter/2 - Length

perimeter = (2*length) + (2*width) length = 2*width so perimeter = (2*2*width) + 2*width = 6*width perimeter = 48 so you can figure out the width and length


Length + length + width + width = perimeter. Length + width x 2 = perimeter


perimeter = 2 x (length + width) ⇒ length + width = perimeter ÷ 2 ⇒ length = (perimeter ÷ 2) - width So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it. IF you meant "What is the length..." then: length = perimeter ÷ 2 - width = 40 ÷ 2 - 2 in = 20 - 2 in = 18 in


Perimeter = 2 lengths + 2 widths 1/2 perimeter = length + width Length = 1/2 perimeter - width Area = length x width That's (1/2 perimeter - width) x (width) .



Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length


The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.


Because the perimeter is lenght + length +width +width, you do perimeter - double the width, and then halve the remaining number. that should give you the length.


Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter


The perimeter is equal to length + length + width + width while area is length x width. Both measurements are found by using width and length.


The perimeter is the total distance around - width + width+ length + length.



Perimeter is Length + width x 2 or Length + length + width + width. This is perimeter for any shape including a rectangle. Perimeter of a rectangle is all sides added together for a rectangle.


call width x so length is 3x perimeter is (2*length)+(2*width) so perimeter is 8x


In the simplified format:Perimeter of a rectangle = (Length) + (Width) + (Length) + (Width)In the advanced format:Perimeter of a rectangle = 2 x (Length + Width)

perimeter = length + length + width + width = 2*length + 2*width = 36 length = 5*width 2*(5*width) + 2*width = 36 12*width = 36 width = 3 length = 15


Length + width = half perimeter = 100". Length is 98", width is 2"


The perimeter of a rectangle is found by the following formula: (Length x 2) + (Width x 2) or Length + Length + Width + Width.


If people say that "perimeter is the length times width" stop listening to them. They don't know what they are talking about.Length times width is the area, not the perimeter. For a square or rectangle, the perimeter is double the sum of the length and the width.


Area = Length*Width so Width = Area/Length. Therefore the Width can be calculated. Then, perimeter = 2*(Length + Width) and everything on the right hand side of the equation is known so the perimeter can be calculated.


Use the following formulae: Area = length x width Perimeter = 2 x length plus 2 x width, or length + length + width + width


Length + width = half of perimeter, so you need more information...


multiply the width by 2 and then subtract that to the perimeter then divide the answer by 2 to get the length
