You can't find the widths of a rectangle with the lengths because the widths can be anything lower than the lengths. Like if your rectangle had a length of 7 the width can be 6, 5, 4, 3, 2, and so on.
To find the perimeter of a rectangle you must calculate the lengths of each of the sides and add them all together.
find all the lengths each side times 4
Add together the lengths of the four sides; or add the lengths of the two different sides and then double it.

2l + 2w = 82 in.
The answer will depend on the figure, the type(s) of symmetry and what information about is is given.
The same way you find the perimeter of a rectangle, add the side lengths
If you are trying to find the ratio of the lengths of two similar rectangles, divide the length of one side of one rectangle by the corresponding side length of the other rectangle. To find the ratio between their volumes, divide the volume of one rectangle by the volume the other rectangle. To find volume, multiply the width of the rectangle by the length of the rectangle.
A matchbox is rectangular in shape. A rectangle has 2 lines of rotational symmetery. So, a matchbox has 2 lines of rotational symmetry.
Add together the lengths of each of its sides.
In order to find the perimeter of a 3D rectangle you must gather the lengths of the known sides, calculate the missing rectangular values, and use the formula for perimeter.
