To find the ratio of the length of a shape to its perimeter, you would divide the length by the perimeter. For example, if the length of a rectangle is 4 units and its perimeter is 12 units, the ratio would be 4/12 or 1/3. This ratio represents the proportion of the length to the total distance around the shape.
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

width = (perimeter-2*length)/2

Length + length + width + width = perimeter. Length + width x 2 = perimeter
If the shape is a rectangle (or square), then Perimeter = 2*(Length + Breadth) So Breadth = Perimeter/2 - Length
Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
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 (P)=2(length+base) find length, area = length * base = (p/2-base)*base
The answer depends on what information you have. If you have the length of a side, then the perimeter is nine times that length.
10cm is a length. You can only find perimeter (length all the way round) if there is a shape!
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.
