if you have the length of one side - plus the perimeter... Divide the perimeter by 2, then subtract the known side - this leaves you with the unknown dimension. For example...
Say you have a side length of 10, and a perimeter of 30. 30/2 = 15, subtract 10 from that - and you get the missing measurement of 5.
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
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.

If the shape is a rectangle, then Perimeter = 2(Length + Width) So Width = Perimeter/2 - Length
Multiply length by width
Length = (Perimeter - twice width) / 2

Perimeter = 2*(L + W).
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.
If the length of a rectangle is twice its width and it has a perimeter of 48, then the rectangle is 16 in length and 8 in width.
If the shape is a rectangle, then Perimeter = 2(Length + Width) So Width = Perimeter/2 - Length
The perimeter of a rectangle whose length is 5cm wit a width of 6cm is 22cm
Multiply length by width
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
