Question: The perimeter of a rectangle is 104  and it's area is 640 . Find the length and breadth.

======================================================

Given,

Perimeter (
) = 104
Area (
) = 640

Let the length be
.

We know,
.

So, one equation is  .

We also know that,

Another equation is,   .

Let's work on the first equation -  .

=>

=>

∴

or,

Now, it's time for the second equation -

We already found on solving the upper equation that  is equal to .
And,  is equal to .

So, we can put any of the values in this equation and simplify to get the desired output (the values of breadth and length).

One way is,

﻿ is equal to .
So,
