#3**+5 **

Sorry Mathsisbae,

you misunderstood my request. (Private message)

I wanted you to make a post here to ask me to explain more .

I did not want you to make another post that was the same - we don't do that. :)

okay you want me to expain some more. :)

The perimeter of the square is 80p+19 and that is in cms

There are 4 sides and they are all the same. when you add up all the sides you will have the perimeter.

So on side must be a quarter of the perimeter.

$$\\side=\frac{1}{4}\times (80p+19)\\\\

side=\frac{80p+19}{4}\;\;cm$$

---------------------------------------------------------

If you are still not sure think about what you would do with something simpler

Say the perimeter is 20cm

then the side would have to be 20/4 = 5cm BECAUSE 5+5+5+5=20cm

------------------------------------------------

This method of replacing something complicated with something easy to work out how to do it is really handy.

I still do this regularly. :)

Does that help ?
