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
The perimeter is the total distance around - width + width+ length + length.
Perimeter: Add the length of the four sides. Area: Multiply length x width.
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.
you do length multiplied by the width
Perimeter = length + width + length + width = 2 x (length + width) Given: perimeter = 22in length = width + 3in Thus 22 = 2 x (width + 3 + width) 11 = 2 x width + 3 8 = 2 x width 4 = width So the width is 4in.
you need length and width length multiply width = area length + length + width + width = perimeter
width = (perimeter-2*length)/2
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
Length + length + width + width = perimeter. Length + width x 2 = perimeter
Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
The perimeter is the total distance around - width + width+ length + length.
Perimeter = Width x 2 + length x 2. To find width, you minus the length from perimeter because opposite of ADD is SUBTRACT.
Length = (Perimeter - twice width) / 2
Length + width = half of perimeter, so you need more information...
You divide the perimeter by the width and you get the lenght
It isn't clear how you would define the "perimeter" for a 3D figure. The base is the product of length x width.
you multiply 2 times the width and 2 times the length ad then add them together. the equation would be 2l+2w=perimeter
