Suppose a farmer has 120 feet of fencing to make a rectangular barnyard enclosure. If the enclosure is x feet long, express the area A of the enclosure as a function of the length x.

  • Algebra - ,

    120 equals x + two ends=x+(120-x) so each end is (120-x)/2

    area is then A=x(120-x)/2

  • Algebra - ,

    So would the answer be

    A(x) = 60x – x^2?

    Or

    A(x) = 120x – x2

  • Algebra - ,

    I get 60x-x^2/2

  • Algebra - ,

    Thanks that is what I got to, so therefore A(x) = 60x – x^2 is the answer! Thanks for your help! :-)
