Translate into equation (no need solution): PLS HELPP The perimeter of a rectangle whose length exceeds thrice its width by 5cm

Miracrown (miracrown):

let's call its width W and its length L: |dw:1411190135548:dw|

Miracrown (miracrown):

We want to relate L and W in an equation So let's look at this sentence: ''length exceeds thrice its width by 5cm''

Miracrown (miracrown):

Let's ignore the thrice part for a second. How can we say Length exceeds width by 5, in the form of an equation?

Miracrown (miracrown):

It should be L = W+5, right? So now let's think about the last part: ''Length exceeds THRICE the width plus 5'' So what do we need to put in our equation at this point?
