You can't: perimeter = 2 x (length + width), assuming you're talking about a rectangle.
width = (perimeter-2*length)/2
Its impossible to isolate both the length and width, but you can figure out the sum of one pair of length and width, which is 13.
area is length times width
You divide the perimeter by the width and you get the lenght
If it's a rectangle, just minus the length from the perimeter twice and than divide what you have by 2. Width = (Perimeter - (length*2))/2
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 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
You can't only using the perimeter. You have to know length and width.
The perimeter is the total distance around - width + width+ length + length.
you need length and width length multiply width = area length + length + width + width = perimeter
Perimeter = Width x 2 + length x 2. To find width, you minus the length from perimeter because opposite of ADD is SUBTRACT.
