er im not sure but it would be like this: 2x + 2y = 500
then you solve for x : 2x = -2y + 500
x = -y + 250

Since there are 2 unknown numbers (X and Y), there wont be an exact value of either one, but you will know the value of the sum and/or product of them (X+Y and X x Y). And that can get you the area. So the equations to get area from just the perimiter are: (equations with a * find possible values for the variables)
P=500
P=X+Y
500=X+Y
500-X=Y
Y=X*
2X=500*
X=500/2*
X=250*
W=500-X*
W=250*
A=X x Y
A=250 x 250*
A=62500
This is confusing but anyways thats the area of the playground. As i said before, the equations with a * mean that they find 1 possible value of X and Y. but no matter what values you get, you will get an area of 62500 units.
