Question

A child care center has 440 feet of fencing to enclose two adjacent rectangular safe play areas. How do you write an expression for the total area A of the play areas in terms of x?

Answer 1

It isn't clear as to the exact configuration, so I've assumed that combined the two play areas make up a single rectangle (as pictured below).
Since you didn't specify what `x` is, I decided to make it the common play area width (also as pictured below).

If the total play area is `A` then
`A(x) = 220x -3/2x^2`
(once more with reference to the diagram)
