Example Question #51 : Rectangles
If the area of the rectangle is 
In order to find the perimeter of a rectangle, you will need to know both length and width. The question, however, only provides us with the width.
Recall how to find the area of the rectangle:
Now, using the area and the given width, we can then find the length.
Plug in the given values.
Now that we have both length and width, find the perimeter of the rectangle.

Example Question #41 : How To Find The Perimeter Of A Rectangle
Find the perimeter of a rectangle given width 4 and length 6.
To solve, simply use the fomula for the perimeter of a square. Thus,
Example Question #42 : How To Find The Perimeter Of A Rectangle
Find the perimeter of a rectangle given width of 6 and length of 8.
The perimeter of a rectangle is found by adding all the side lengths together. In a rectangle there are two widths and two lengths.
In other words, simply use the formula for the perimeter of a rectangle and let,
Thus,
Example Question #43 : How To Find The Perimeter Of A Rectangle
Find the perimeter of a rectangle with width 9 and length 1.
To solve, simply use the formula for the perimeter of a rectangle. Thus,
Example Question #41 : How To Find The Perimeter Of A Rectangle
A Quidditch field is rectangular in shape and boasts a width of 
To solve for the perimeter of the Quidditch field, we must first determine the length of the field. With the provided information, we can solve for this by drafting an algebraic equation:
Now that we know our length, we can determine the perimeter of the field:
Example Question #468 : Basic Geometry
A football field is rectangular in shape. The length of the field is 100 yards and the width of the field is 50 yards. What is the length of the perimeter?
A rectangle has the same length on either side and the same width on either side. Therefore if the football field has 100 yards in length and 50 yards in width you can use this formula.
