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.
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.
The width is 10.5 cm.
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.
Length + width = half of perimeter, so you need more information...
Length = (Perimeter - twice width) / 2
Perimeter = Width x 2 + length x 2. To find width, you minus the length from perimeter because opposite of ADD is SUBTRACT.
You divide the perimeter by the width and you get the lenght
To find the length given the perimeter of a rectangle, you would need the width as well. Since the perimeter of a rectangle is the sum of all its sides (2 lengths + 2 widths), you can rearrange the formula to solve for the length by subtracting twice the width from the perimeter and dividing the result by 2. Formula: Length = (Perimeter - 2*width) / 2.
It isn't clear how you would define the "perimeter" for a 3D figure. The base is the product of length x width.
