The question goes like this:

''A rectangular playground has a perimeter of $\displaystyle 60m$ and an area of $\displaystyle 216m^2$. Find the dimensions of the playground.''

What I did is this (perimeter):

Let the length be $\displaystyle x$ meters and the breadth be $\displaystyle y$ metres.

From the given information,

$\displaystyle 2x + 2y = 60$

$\displaystyle 2x +2y -60 = 0$

That was when I got stuck in this status quo...

It's common sense that I couldn't solve that equation.

Now if I were to take another way, which is the equation of the area of the playground:

$\displaystyle

(x^2)(y^2)= 216$

$\displaystyle x^2y^2 -216 = 0$

I still couldn't solve this...

Can anyone help me to solve this question? Thank you so much for taking your time!
