(a) If the sides perpendicular to the wall have length x feet, which of the following represents the area A of the garden?

A(x) = –2x2 + 30x

A(x) = –2x2 + 60x

A(x) = x2 – 60x

A(x) = 2x2 – 60x

Area = length * width

If x = length of each of the two sides, then the width = 60 - 2x

Thus the area = x(60-2x) = 60x - 2x^2

Unless you have a typo, I would not pick any of the choices.
