**bobpursley**, Wednesday, June 17, 2009 at 2:50pmif length is x, then width is (120-2x)/2

Area is then length x width or

x * (60-x)

**Breanna**, Wednesday, June 17, 2009 at 2:55pmA(x) = 60x x2

A(x) = 120x x2

A(x) = x2 30x

Are any of these the answers?

**Breanna**, Wednesday, June 17, 2009 at 2:56pmThe 2 meaning squared of course so

A(x) = 60x x^2

A(x) = 120x x^2

A(x) = x^2 30x

**Breanna**, Wednesday, June 17, 2009 at 3:45pmSo A is the answer then?

A(x) = 60x x^2

This was my first guess, was I correct?
