I am revising for Higher maths sqa assessment in May and have forgotten how to do this can someone help.
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
