The area of a rectangular athletic field is represented by the expression square meters. Write an algebraic expression to represent one possible set of dimensions (in the sense Òlength times widthÓ) of the athletic field. Include correct units with your solution.

The answer I have is (8y+5z)(8y-5z).

I still am not sure how to include correct units in the solution. Please help!

  • Algebra - ,

    do the FOIL method
    f for first
    o for outer
    i for inner
    l for last

    (8y+5z)(8y-5z)

    64y^2 + 40yz - 40yz + -25z^2

    64y^2 - 25z^2
