A farmer uses 60 metres of fencing to form a rectangular pen in a field:

a) given that the pen has breadth x cm find an expression for its area.

I worked out 60x - 2x^2 which is wrong but I dont know why.

b) find the greatest area that can be enclosed by the pen.

Cant work this out without correct answer to a)

Appreciate any help, Michelle
