The perimeter of a rectangle is given by where is the length and is the width. You are given that the length is 14 more than the width, so you can say , and you are given that . So take the equation for the perimeter:

and substitute:

Now all you have to do is solve that equation for W to get the width, and add 14 to that answer to get the length.

We have to start with formula of finding the Perimeter of Rectangle:
-----------> eqn 1
.
Next, label the given:
W= unknown
L= W+14, right? (14 more)
P= 264 meters
Substituting in eqn 1,
264= 2(W+14+W)
264= 2(2W+14)=4W+28

For L = 59+14

In doubt? Go back eqn 1,

Thank you,
Jojo

The opposite sides of a rectangle are equal
They could be 12,12,5 , and 5
or 33,33,8, and 8
or a, a, b, and b
The problem says the perimeter is meters, so
meters
If is the length and is the width,
meters
Plug this expression for into the 1st equation

The length is 73 meters and the width is 59 meters
check answer:

and

OK
