The perimeter of a rectangle is twice the sum of its length and its width. The perimeter is 28 meters and its length is 2 meters more than twice it's width.

What is it's Length?

The perimeter of the rectangle

=

28

meters.

Let the width be denoted as

x

,

The length

=

2

+

(length is 2 meters more than twice the width)

The formula for perimeter of a rectangle is:

perimeter =

2
