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
you need length and width length multiply width = area length + length + width + width = perimeter
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
Perimeter: Add the length of the four sides. Area: Multiply length x width.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
